bcachefs updates for 6.15
On disk format is now soft frozen: no more required/automatic are
anticipated before taking off the experimental label.
Major changes/features since 6.14:
- Scrub
- Blocksize greater than page size support
- A number of "rebalance spinning and doing no work" issues have been
fixed; we now check if the write allocation will succeed in
bch2_data_update_init(), before kicking off the read.
There's still more work to do in this area. Later we may want to add
another bitset btree, like rebalance_work, to track "extents that
rebalance was requested to move but couldn't", e.g. due to destination
target having insufficient online devices.
- We can now support scaling well into the petabyte range: latest
bcachefs-tools will pick an appropriate bucket size at format time to
ensure fsck can run in available memory (e.g. a server with 256GB of
ram and 100PB of storage would want 16MB buckets).
On disk format changes:
- 1.21: cached backpointers (scalability improvement)
Cached replicas now get backpointers, which means we no longer rely on
incrementing bucket generation numbers to invalidate cached data: this
lets us get rid of the bucket generation number garbage collection,
which had to periodically rescan all extents to recompute bucket
oldest_gen.
Bucket generation numbers are now only used as a consistency check,
but they're quite useful for that.
- 1.22: stripe backpointers
Stripes now have backpointers: erasure coded stripes have their own
checksums, separate from the checksums for the extents they contain
(and stripe checksums also cover the parity blocks). This is required
for implementing scrub for stripes.
- 1.23: stripe lru (scalability improvement)
Persistent lru for stripes, ordered by "number of empty blocks". This
is used by the stripe creation path, which depending on free space
may create a new stripe out of a partially empty existing stripe
instead of starting a brand new stripe.
This replaces an in-memory heap, and means we no longer have to read
in the stripes btree at startup.
- 1.24: casefolding
Case insensitive directory support, courtesy of Valve.
This is an incompatible feature, to enable mount with
-o version_upgrade=incompatible
- 1.25: extent_flags
Another incompatible feature requiring explicit opt-in to enable.
This adds a flags entry to extents, and a flag bit that marks extents
as poisoned.
A poisoned extent is an extent that was unreadable due to checksum
errors. We can't move such extents without giving them a new checksum,
and we may have to move them (for e.g. copygc or device evacuate).
We also don't want to delete them: in the future we'll have an API
that lets userspace ignore checksum errors and attempt to deal with
simple bitrot itself. Marking them as poisoned lets us continue to
return the correct error to userspace on normal read calls.
Other changes/features:
- BCH_IOCTL_QUERY_COUNTERS: this is used by the new 'bcachefs fs top'
command, which shows a live view of all internal filesystem counters.
- Improved journal pipelining: we can now have 16 journal writes in
flight concurrently, up from 4. We're logging significantly more to
the journal than we used to with all the recent disk accounting
changes and additions, so some users should see a performance
increase on some workloads.
- BCH_MEMBER_STATE_failed: previously, we would do no IO at all to
devices marked as failed. Now we will attempt to read from them, but
only if we have no better options.
- New option, write_error_timeout: devices will be kicked out of the
filesystem if all writes have been failing for x number of seconds.
We now also kick devices out when notified by blk_holder_ops that
they've gone offline.
- Device option handling improvements: the discard option should now be
working as expected (additionally, in -tools, all device options that
can be set at format time can now be set at device add time, i.e.
data_allowed, state).
- We now try harder to read data after a checksum error: we'll do
additional retries if necessary to a device after after it gave us
data with a checksum error.
- More self healing work: the full inode <-> dirent consistency checks
that are currently run by fsck are now also run every time we do a
lookup, meaning we'll be able to correct errors at runtime. Runtime
self healing will be flipped on after the new changes have seen more
testing, currently they're just checking for consistency.
- KMSAN fixes: our KMSAN builds should be nearly clean now, which will
put a massive dent in the syzbot dashboard.

Could you please consider this pull request? Thanks, f2fs-for-6.15-rc1 In this round, there are three major updates: 1) folio conversion, 2) refactor for mount API conversion, 3) some performance improvement such as direct IO, checkpoint speed, and IO priority hints. For stability, there are patches which add more sanity checks and fixes some major issues like i_size in atomic write operations and write pointer recovery in zoned devices. Enhancement: - huge folio converion work by Matthew Wilcox - clean up for mount API conversion by Eric Sandeen - improve direct IO speed in the overwrite case - add some sanity check on node consistency - set highest IO priority for checkpoint thread - keep POSIX_FADV_NOREUSE ranges and add sysfs entry to reclaim pages - add ioctl to get IO priority hint - add carve_out sysfs node for fsstat Bug fix: - disable nat_bits during umount to avoid potential nat entry corruption - fix missing i_size update on atomic writes - fix missing discard for active segments - fix running out of free segments - fix out-of-bounds access in f2fs_truncate_inode_blocks() - call f2fs_recover_quota_end() correctly - fix potential deadloop in prepare_compress_overwrite() - fix the missing write pointer correction for zoned device - fix to avoid panic once fallocation fails for pinfile - don't retry IO for corrupted data scenario There are many other clean up patches and minor bug fixes as usual.
Hi,
please pull the following btrfs updates, thanks.
User visible changes:
- fall back to buffered write if direct io is done on a file that requires
checksums
- this avoids a problem with checksum mismatch errors, observed e.g. on
virtual images when writes to pages under writeback cause the checksum
mismatch reports
- this may lead to some performance degradation but currently the
recommended setup for VM images is to use the NOCOW file attribute that
also disables checksums
- fast/realtime zstd levels -15 to -1
- supported by mount options (compress=zstd:-5) and defrag ioctl
- improved speed, reduced compression ratio, check the commit for sample
measurements
- defrag ioctl extended to accept negative compression levels
- subpage mode
- remove warning when subpage mode is used, the feature is now reasonably
complete and tested
- in debug mode allow to create 2K b-tree nodes to allow testing subpage on
x86_64 with 4K pages too
Performance improvements:
- in send, better file path caching improves runtime (on sample load by -30%)
- on s390x with hardware zlib support prepare the input buffer in a better way
to get the best results from the acceleration
- minor speed improvement in encoded read, avoid memory allocation in
synchronous mode
Core:
- enable stable writes on inodes, replacing manually waiting for writeback
and allowing to skip that on inodes without checksums
- add last checks and warnings for out-of-band dirty writes to pages,
requiring a fixup ("fixup worker"), this should not be necessary since 5.8
where get_user_page() and pin_user_pages*() prevent this
- long history behind that, we'll be happy to remove the whole infrastructure
in the near future
- more folio API conversions and preparations for large folio support
- subpage cleanups and refactoring, split handling of data and metadata to
allow future support for large folios
- readpage works as block-by-block, no change for normal mode, this is
preparation for future subpage updates
- block group refcount fixes and hardening
- delayed iput fixes
- in zoned mode, fix zone activation on filesystem with missing devices
- cleanups:
- inode parameter cleanups
- path auto-freeing updates
- code flow simplifications in send
- redundant parameter cleanups
pm-6.15-rc1 Merge branch 'pm-misc' Linux 6.14-rc6 to receive power management updates for 6.15-rc1. These are dominated by cpufreq updates which in turn are dominated by updates related to boost support in the core and drivers and amd-pstate driver optimizations. Apart from the above, there are some cpuidle updates including a rework of the most recent idle intervals handling in the venerable menu governor that leads to significant improvements in some performance benchmarks, as the governor is now more likely to predict a shorter idle duration in some cases, and there are updates of the core device power management code, mostly related to system suspend and resume, that should help to avoid potential issues arising when the drivers of devices depending on one another want to use different optimizations. There is also a usual collection of assorted fixes and cleanups, including removal of some unused code. Specifics: - Manage sysfs attributes and boost frequencies efficiently from cpufreq core to reduce boilerplate code in drivers (Viresh Kumar). - Minor cleanups to cpufreq drivers (Aaron Kling, Benjamin Schneider, Dhananjay Ugwekar, Imran Shaik, zuoqian). - Migrate some cpufreq drivers to using for_each_present_cpu() (Jacky Bai). - cpufreq-qcom-hw DT binding fixes (Krzysztof Kozlowski). - Use str_enable_disable() helper in cpufreq_online() (Lifeng Zheng). - Optimize the amd-pstate driver to avoid cases where call paths end up calling the same writes multiple times and needlessly caching variables through code reorganization, locking overhaul and tracing adjustments (Mario Limonciello, Dhananjay Ugwekar). - Make it possible to avoid enabling capacity-aware scheduling (CAS) in the intel_pstate driver and relocate a check for out-of-band (OOB) platform handling in it to make it detect OOB before checking HWP availability (Rafael Wysocki). - Fix dbs_update() to avoid inadvertent conversions of negative integer values to unsigned int which causes CPU frequency selection to be inaccurate in some cases when the "conservative" cpufreq governor is in use (Jie Zhan). - Update the handling of the most recent idle intervals in the menu cpuidle governor to prevent useful information from being discarded by it in some cases and improve the prediction accuracy (Rafael Wysocki). - Make it possible to tell the intel_idle driver to ignore its built-in table of idle states for the given processor, clean up the handling of auto-demotion disabling on Baytrail and Cherrytrail chips in it, and update its MAINTAINERS entry (David Arcari, Artem Bityutskiy, Rafael Wysocki). - Make some cpuidle drivers use for_each_present_cpu() instead of for_each_possible_cpu() during initialization to avoid issues occurring when nosmp or maxcpus=0 are used (Jacky Bai). - Clean up the Energy Model handling code somewhat (Rafael Wysocki). - Use kfree_rcu() to simplify the handling of runtime Energy Model updates (Li RongQing). - Add an entry for the Energy Model framework to MAINTAINERS as properly maintained (Lukasz Luba). - Address RCU-related sparse warnings in the Energy Model code (Rafael Wysocki). - Remove ENERGY_MODEL dependency on SMP and allow it to be selected when DEVFREQ is set without CPUFREQ so it can be used on a wider range of systems (Jeson Gao). - Unify error handling during runtime suspend and runtime resume in the core to help drivers to implement more consistent runtime PM error handling (Rafael Wysocki). - Drop a redundant check from pm_runtime_force_resume() and rearrange documentation related to __pm_runtime_disable() (Rafael Wysocki). - Rework the handling of the "smart suspend" driver flag in the PM core to avoid issues that may occur when drivers using it depend on some other drivers and clean up the related PM core code (Rafael Wysocki, Colin Ian King). - Fix the handling of devices with the power.direct_complete flag set if device_suspend() returns an error for at least one device to avoid situations in which some of them may not be resumed (Rafael Wysocki). - Use mutex_trylock() in hibernate_compressor_param_set() to avoid a possible deadlock that may occur if the "compressor" hibernation module parameter is accessed during the registration of a new ieee80211 device (Lizhi Xu). - Suppress sleeping parent warning in device_pm_add() in the case when new children are added under a device with the power.direct_complete set after it has been processed by device_resume() (Xu Yang). - Remove needless return in three void functions related to system wakeup (Zijun Hu). - Replace deprecated kmap_atomic() with kmap_local_page() in the hibernation core code (David Reaver). - Remove unused helper functions related to system sleep (David Alan Gilbert). - Clean up s2idle_enter() so it does not lock and unlock CPU offline in vain and update comments in it (Ulf Hansson). - Clean up broken white space in dpm_wait_for_children() (Geert Uytterhoeven). - Update the cpupower utility to fix lib version-ing in it and memory leaks in error legs, remove hard-coded values, and implement CPU physical core querying (Thomas Renninger, John B. Wyatt IV, Shuah Khan, Yiwei Lin, Zhongqiu Han). Thanks!
thermal-6.15-rc1 Linux 6.14-rc6 to receive thermal control updates for 6.15-rc1. These include one thermal core fix for an issue leading to a NULL pointer dereference, a similar fix for the int340x thermal driver (even though the issue may not actually occur in practice in this particular case), and a bunch of cleanups, mostly related to replacing kzalloc() with kcalloc() where applicable: - Delay exposing thermal zone sysfs interface to prevent user space from accessing thermal zones that have not been completely initialized yet (Lucas De Marchi). - Check a pointer against NULL early in int3402_thermal_probe() to avoid a potential NULL pointer dereference (Chenyuan Yang). - Use kcalloc() instead of kzalloc() in some places in the thermal control subsystem (Lukasz Luba, Ethan Carter Edwards). - Fix a spelling mistake in a comment in the thermal core (Colin Ian King). - Clean up variable initialization in int340x_thermal_zone_add() (Christophe JAILLET). Thanks!
acpi-6.15-rc1 Linux 6.14-rc6 to receive ACPI updates for 6.15-rc1. From the functional perspective, the most significant changes here are the ACPI fan driver update allowing it to handle fans with fine-grained state checking supported, but without fine-grained control, and the ACPI button driver update making it subscribe to system event notifications (in addition to device notifications) which on some systems is requisite for waking up the system from sleep. The rest is fixes and cleanups including removal of some dead code. Specifics: - Use the str_on_off() helper function instead of hard-coded strings in the ACPI power resources handling code (Thorsten Blum). - Add fan speed reporting for ACPI fans that have _FST, but otherwise do not support the entire ACPI 4 fan interface (Joshua Grisham). - Fix a stale comment regarding trip points in acpi_thermal_add() that diverged from the commented code after removing _CRT evaluation from acpi_thermal_get_trip_points() (xueqin Luo). - Make ACPI button driver also subscribe to system events (Mario Limonciello). - Use the str_yes_no() helper function instead of hard-coded strings in the ACPI backlight (video) driver (Thorsten Blum). - Add a missing header file include to the x86 arch CPPC code (Mario Limonciello). - Rework the sysfs attributes implementation in the ACPI platform-profile driver and improve the unregistration code in it (Nathan Chancellor, Kurt Borja). - Prevent the ACPI HED driver from being built as a module and change its initcall level to subsys_initcall to avoid initialization ordering issues related to it (Xiaofei Tan). - Update a maintainer email address in the ACPI PMIC entry in MAINTAINERS (Mika Westerberg). - Address a GCC 15's -Wunterminated-string-initialization warning in the core PNP subsystem code and remove some dead code from it (Kees Cook, David Alan Gilbert). Thanks!
spi: Updates for v6.15 The biggest change for SPI this release is the addition of offload support from David Lechner, allowing the hardware to trigger SPI transactions autonomously. The initial use case is for triggering IIO operations but there are other applications where having the hardware ready to go at a minimal signal is useful for synchronising with external inputs (eg, interrupt handling) or reducing latency (eg, CAN networking). Otherwise there's the usual fixes, improvements and cleanups, plus support for a bunch of new devices. - Support for offloaing support from David Lechner. - Support for GOcontrol1 Moduline modules, Mediatek MT7988, NXP i.MX94, Qualcomm SPI NAMD, Rockchip RK3562, Sophogo SG2044 and ST STM32 OSPI.
regulator: Updates for v6.15 This has been a very quiet release, we've got support for one device added, another removed, and some smaller fixes and API improvements. The main thing of note is the rework of the PCA9450 LDO5 handling: - A rework of the handling of LDO5 on the PCA9450, this was quite wrong in how it handled the SD_VSEL conrol and only worked for some system designs. This includes a DTS update since there was a not quite ABI compatible change as part of the fix. - A devres change introducing devm_kmemdup_array() was pulled in so it could be used with some regulator conversions to that function, this pulled in some other devres and IIO stuff that was part of the same pull request. - Removal of the PCF50633 driver, the SoC for the OpenMoko platform that used it has been removed. - Support for the NXP PF9453.
Another set of improvements to the kernel's CRC (cyclic redundancy check) code: - Rework the CRC64 library functions to be directly optimized, like what I did last cycle for the CRC32 and CRC-T10DIF library functions. - Rewrite the x86 PCLMULQDQ-optimized CRC code, and add VPCLMULQDQ support and acceleration for crc64_be and crc64_nvme. - Rewrite the riscv Zbc-optimized CRC code, and add acceleration for crc_t10dif, crc64_be, and crc64_nvme. - Remove crc_t10dif and crc64_rocksoft from the crypto API, since they are no longer needed there. - Rename crc64_rocksoft to crc64_nvme, as the old name was incorrect. - Add kunit test cases for crc64_nvme and crc7. - Eliminate redundant functions for calculating the Castagnoli CRC32, settling on just crc32c(). - Remove unnecessary prompts from some of the CRC kconfig options. - Further optimize the x86 crc32c code.
A fix for an issue where CONFIG_FS_VERITY could be enabled without some of its dependencies, and a small documentation update.
A fix for an issue where CONFIG_FS_ENCRYPTION could be enabled without some of its dependencies, and a small documentation update.

Updates for the VDSO infrastructure:
- Consolidate the VDSO storage=20
=20
The VDSO data storage and data layout has been largely architecture
specific for historical reasons. That increases the maintenance effort
and causes inconsistencies over and over.
There is no real technical reason for architecture specific layouts and
implementations. The architecture specific details can easily be
integrated into a generic layout, which also reduces the amount of
duplicated code for managing the mappings.
Convert all architectures over to a unified layout and common mapping
infrastructure. This splits the VDSO data layout into subsystem
specific blocks, timekeeping, random and architecture parts, which
provides a better structure and allows to improve and update the
functionalities without conflict and interaction.
- Rework the timekeeping data storage
The current implementation is designed for exposing system timekeeping
accessors, which was good enough at the time when it was designed.
PTP and Time Sensitive Networking (TSN) change that as there are
requirements to expose independent PTP clocks, which are not related to
system timekeeping.
Replace the monolithic data storage by a structured layout, which
allows to add support for independent PTP clocks on top while reusing
both the data structures and the time accessor implementations.
Note: There is a trivial conflict vs. the x86/core pull request, which
changes a VDSO random implementation detail.

Updates for interrupt chip drivers:
- Support for hard indices on RISC-V. The hart index identifies a hart
(core) within a specific interrupt domain in RISC-V's Priviledged
Architecture.
- Rework of the RISC-V MSI driver.
This moves the driver over to the generic MSI library and solves the
affinity problem of unmaskable PCI/MSI controllers. Unmaskable PCI/MSI
controllers are prone to lose interrupts when the MSI message is
updated to change the affinity because the message write consists of
three 32-bit subsequent writes, which update address and data. As these
writes are non-atomic versus the device raising an interrupt, the
device can observe a half written update and issue an interrupt on the
wrong vector. This is mitiated by a carefully orchestrated step by step
update and the observation of an eventually pending interrupt on the
CPU which issues the update. The algorithm follows the well established
method of the X86 MSI driver.
- A new driver for the RISC-V Sophgo SG2042 MSI controller
- Overhaul of the Renesas RZQ2L driver.
Simplification of the probe function by using devm_*() mechanisms,
which avoid the endless list of error prone gotos in the failure paths.
- Expand the Renesas RZV2H driver to support RZ/G3E SoCs
- A workaround for Rockchip 3568002 erratum in the GIC-V3 driver to
ensure that the addressing is limited to the lower 32-bit of the
physical address space.
- Add support for the Allwinner AS23 NMI controller
- Expand the IMX irqsteer driver to handle up to 960 input interrupts
- The usual small updates, cleanups and device tree changes.

ith other clockids
Updates for the core time/timer subsystem:
- Fix a memory ordering issue in posix-timers
Posix-timer lookup is lockless and reevaluates the timer validity under
the timer lock, but the update which validates the timer is not
protected by the timer lock. That allows the store to be reordered
against the initialization stores, so that the lookup side can observe
a partially initialized timer. That's mostly a theoretical problem, but
incorrect nevertheless.
- Fix a long standing inconsistency of the coarse time getters
The coarse time getters read the base time of the current update cycle
without reading the actual hardware clock. NTP frequency adjustment can
set the base time backwards. The fine grained interfaces compensate
this by reading the clock and applying the new conversion factor, but
the coarse grained time getters use the base time directly. That allows
the user to observe time going backwards.
Cure it by always forwarding base time, when NTP changes the frequency
with an immediate step.
- Rework of posix-timer hashing
The posix-timer hash is not scalable and due to the CRIU timer restore
mechanism prone to massive contention on the global hash bucket lock.
Replace the global hash lock with a fine grained per bucket locking
scheme to address that.
- Rework the proc/$PID/timers interface.
/proc/$PID/timers is provided for CRIU to be able to restore a
timer. The printout happens with sighand lock held and interrupts
disabled. That's not required as this can be done with RCU protection
as well.
- Provide a sane mechanism for CRIU to restore a timer ID
CRIU restores timers by creating and deleting them until the kernel
internal per process ID counter reached the requested ID. That's
horribly slow for sparse timer IDs.
Provide a prctl() which allows CRIU to restore a timer with a given
ID. When enabled the ID pointer is used as input pointer to read the
requested ID from user space. When disabled, the normal allocation
scheme (next ID) is active as before. This is backwards compatible for
both kernel and user space.
- Make hrtimer_update_function() less expensive.
The sanity checks are valuable, but expensive for high frequency usage
in io/uring. Make the debug checks conditional and enable them only
when lockdep is enabled.

- Clarify RCU_LAZY and RCU_LAZY_DEFAULT_OFF help text.
- Remove references to old grace-period-wait primitives.
srcu.2025.02.05a:
- Introduce srcu_read_{un,}lock_fast(), which is similar to
srcu_read_{un,}lock_lite(): avoid smp_mb()s in lock and unlock at the
cost of calling synchronize_rcu() in synchronize_srcu(). Moreover, by
returning the percpu offset of the counter at srcu_read_lock_fast()
time, srcu_read_unlock_fast() can save extra pointer dereferencing,
which makes it faster than srcu_read_{un,}lock_lite().
srcu_read_{un,}lock_fast() are intended to replace
rcu_read_{un,}lock_trace() if possible.
torture.2025.02.05a:
- Add get_torture_init_jiffies() to return the start time of the test.
- Add a test_boost_holdoff module parameter to allow delaying boosting
tests when building rcutorture as built-in.
- Add grace period sequence number logging at the beginning and end of
failure/close-call results.
- Switch to hexadecimal for the expedited grace period sequence number
in the rcu_exp_grace_period trace point.
- Make cur_ops->format_gp_seqs take buffer length.
- Move RCU_TORTURE_TEST_{CHK_RDR_STATE,LOG_CPU} to bool.
- Complain when invalid SRCU reader_flavor is specified.
- Add FORCE_NEED_SRCU_NMI_SAFE Kconfig for testing, which forces SRCU
uses atomics even when percpu ops are NMI safe, and use the Kconfig
for SRCU lockdep testing.
misc.2025.03.04a:
- Split rcu_report_exp_cpu_mult() mask parameter and use for tracing.
- Remove READ_ONCE() for rdp->gpwrap access in __note_gp_changes().
- Fix get_state_synchronize_rcu_full() GP-start detection.
- Move RCU Tasks self-tests to core_initcall().
- Print segment lengths in show_rcu_nocb_gp_state().
- Make RCU watch ct_kernel_exit_state() warning.
- Flush console log from kernel_power_off().
- rcutorture: Allow a negative value for nfakewriters.
- rcu: Update TREE05.boot to test normal synchronize_rcu().
- rcu: Use _full() API to debug synchronize_rcu().
lazypreempt.2025.03.04a: Make RCU handle PREEMPT_LAZY better:
- Fix header guard for rcu_all_qs().
- rcu: Rename PREEMPT_AUTO to PREEMPT_LAZY.
- Update __cond_resched comment about RCU quiescent states.
- Handle unstable rdp in rcu_read_unlock_strict().
- Handle quiescent states for PREEMPT_RCU=n, PREEMPT_COUNT=y.
- osnoise: Provide quiescent states.
- Adjust rcutorture with possible PREEMPT_RCU=n && PREEMPT_COUNT=y
combination.
- Limit PREEMPT_RCU configurations.
- Make rcutorture senario TREE07 and senario TREE10 use PREEMPT_LAZY=y.
Hi Wolfram, Here we go with the pull request for the merge window. It's not a huge batch in terms of patch count, but a few pieces of long standing work finally reached the finish line. Some patches are refreshed from the past, something I plan to do more often going forward. One new driver was added: Spacemit K1. Andy has also been very active, contributing the new i2c_10bit_addr_*_from_msg() helper, which is now being adopted across several drivers. I don't think I've missed anything from the recent submissions, and I'm happy to have caught up with the pending work. So I don't expect the need for a part 2 pull request next week. Thanks, and I wish you a great weekend!

Objtool changes for v6.15: - The biggest change is the new option to automatically fail the build on objtool warnings: CONFIG_OBJTOOL_WERROR. While there are no currently known unfixed false positives left, such an expansion in the severity of objtool warnings inevitably creates a risk of build failures, so it's disabled by default and depends on !COMPILE_TEST, so it shouldn't be enabled on allyesconfig/allmodconfig builds and won't be forced on people who just accept build-time defaults in 'make oldconfig'. While the option is strongly recommended, only people who enable it explicitly should see it. (Josh Poimboeuf) - Disable branch profiling in noinstr code with a broad brush that includes all of arch/x86/ and kernel/sched/. (Josh Poimboeuf) - Create backup object files on objtool errors and print exact objtool arguments to make failure analysis easier (Josh Poimboeuf) - Improve noreturn handling (Josh Poimboeuf) - Improve rodata handling (Tiezhu Yang) - Support jump tables, switch tables and goto tables on LoongArch (Tiezhu Yang) - Misc cleanups and fixes (Josh Poimboeuf, David Engraf, Ingo Molnar) Thanks, Ingo

- Fix might_fault() lockdep check of current->mm->mmap_lock (Peter Zijlstra)
- Don't disable interrupts on RT in disable_irq_nosync_lockdep.*()

Once the v6.15 merge window opens, please pull this stop-machine update from: stop-machine: Add a comment for rcu_momentary_eqs() Changes ------- * Add a comment for the call to rcu_momentary_eqs() from multi_cpu_stop() explaining that its purpose is to suppress false-positive RCU CPU stall warnings.
Once the v6.15 merge window opens, please pull the latest nolibc changes from: nolibc changes for 6.15 Changes ------- * 32bit s390 support * opendir() and friends * openat() support * sscanf() support * various cleanups
When the v6.15 merge window opens, please pull this LKMM update from: lkmm: Add more atomic operations, rework tags, and update documentation Changes ------- * Adds additional atomic operations (Puranjay Mohan) * Makes better use of herd7 tags (Jonas Oberhauser) * Updates documentation (Akira Yokosawa) These changes require v7.58 of the herd7 and klitmus tools, up from v7.52.
It has been a reasonably busy cycle for docs... - Significant changes throughout the tree to bring Python code up to current standards and raise the minimum Python required to 3.9. Much of this is preparatory to replacing the ancient Perl scripts/kernel-doc horror with a slightly less horrifying Python implementation, expected for 6.16. - Update the minimum Sphinx required to 3.4.3, allowing us to remove a bunch of older compatibility code. - Rework and improve the generation of the ABI documentation. (All of the above done by Mauro) - Lots of translation updates. Alex Shi and Yanteng Si are taking on responsibility for the Chinese translations going forward; that work will still get to you via docs-next - Try to standardize the format for indicating a developer's affiliation in commit tags. - Clarify the TAB's role in CoC enforcement actions. - Try to spell out the rules for when a commit tag can name another developer without their explicit permission. Plus lots of other typo fixes and updates.
ARM:
* Nested virtualization support for VGICv3, giving the nested
hypervisor control of the VGIC hardware when running an L2 VM
* Removal of 'late' nested virtualization feature register masking,
making the supported feature set directly visible to userspace
* Support for emulating FEAT_PMUv3 on Apple silicon, taking advantage
of an IMPLEMENTATION DEFINED trap that covers all PMUv3 registers
* Paravirtual interface for discovering the set of CPU implementations
where a VM may run, addressing a longstanding issue of guest CPU
errata awareness in big-little systems and cross-implementation VM
migration
* Userspace control of the registers responsible for identifying a
particular CPU implementation (MIDR_EL1, REVIDR_EL1, AIDR_EL1),
allowing VMs to be migrated cross-implementation
* pKVM updates, including support for tracking stage-2 page table
allocations in the protected hypervisor in the 'SecPageTable' stat
* Fixes to vPMU, ensuring that userspace updates to the vPMU after
KVM_RUN are reflected into the backing perf events
LoongArch:
* Remove unnecessary header include path
* Assume constant PGD during VM context switch
* Add perf events support for guest VM
RISC-V:
* Disable the kernel perf counter during configure
* KVM selftests improvements for PMU
* Fix warning at the time of KVM module removal
x86:
* Add support for aging of SPTEs without holding mmu_lock. Not taking mmu_lock
allows multiple aging actions to run in parallel, and more importantly avoids
stalling vCPUs. This includes an implementation of per-rmap-entry locking;
aging the gfn is done with only a per-rmap single-bin spinlock taken, whereas
locking an rmap for write requires taking both the per-rmap spinlock and
the mmu_lock.
Note that this decreases slightly the accuracy of accessed-page information,
because changes to the SPTE outside aging might not use atomic operations
even if they could race against a clear of the Accessed bit. This is
deliberate because KVM and mm/ tolerate false positives/negatives for
accessed information, and testing has shown that reducing the latency of
aging is far more beneficial to overall system performance than providing
"perfect" young/old information.
* Defer runtime CPUID updates until KVM emulates a CPUID instruction, to
coalesce updates when multiple pieces of vCPU state are changing, e.g. as
part of a nested transition.
* Fix a variety of nested emulation bugs, and add VMX support for synthesizing
nested VM-Exit on interception (instead of injecting #UD into L2).
* Drop "support" for async page faults for protected guests that do not set
SEND_ALWAYS (i.e. that only want async page faults at CPL3)
* Bring a bit of sanity to x86's VM teardown code, which has accumulated
a lot of cruft over the years. Particularly, destroy vCPUs before
the MMU, despite the latter being a VM-wide operation.
* Add common secure TSC infrastructure for use within SNP and in the
future TDX
* Block KVM_CAP_SYNC_REGS if guest state is protected. It does not make
sense to use the capability if the relevant registers are not
available for reading or writing.
* Don't take kvm->lock when iterating over vCPUs in the suspend notifier to
fix a largely theoretical deadlock.
* Use the vCPU's actual Xen PV clock information when starting the Xen timer,
as the cached state in arch.hv_clock can be stale/bogus.
* Fix a bug where KVM could bleed PVCLOCK_GUEST_STOPPED across different
PV clocks; restrict PVCLOCK_GUEST_STOPPED to kvmclock, as KVM's suspend
notifier only accounts for kvmclock, and there's no evidence that the
flag is actually supported by Xen guests.
* Clean up the per-vCPU "cache" of its reference pvclock, and instead only
track the vCPU's TSC scaling (multipler+shift) metadata (which is moderately
expensive to compute, and rarely changes for modern setups).
* Don't write to the Xen hypercall page on MSR writes that are initiated by
the host (userspace or KVM) to fix a class of bugs where KVM can write to
guest memory at unexpected times, e.g. during vCPU creation if userspace has
set the Xen hypercall MSR index to collide with an MSR that KVM emulates.
* Restrict the Xen hypercall MSR index to the unofficial synthetic range to
reduce the set of possible collisions with MSRs that are emulated by KVM
(collisions can still happen as KVM emulates Hyper-V MSRs, which also reside
in the synthetic range).
* Clean up and optimize KVM's handling of Xen MSR writes and xen_hvm_config.
* Update Xen TSC leaves during CPUID emulation instead of modifying the CPUID
entries when updating PV clocks; there is no guarantee PV clocks will be
updated between TSC frequency changes and CPUID emulation, and guest reads
of the TSC leaves should be rare, i.e. are not a hot path.
x86 (Intel):
* Fix a bug where KVM unnecessarily reads XFD_ERR from hardware and thus
modifies the vCPU's XFD_ERR on a #NM due to CR0.TS=1.
* Pass XFD_ERR as the payload when injecting #NM, as a preparatory step
for upcoming FRED virtualization support.
* Decouple the EPT entry RWX protection bit macros from the EPT Violation
bits, both as a general cleanup and in anticipation of adding support for
emulating Mode-Based Execution Control (MBEC).
* Reject KVM_RUN if userspace manages to gain control and stuff invalid guest
state while KVM is in the middle of emulating nested VM-Enter.
* Add a macro to handle KVM's sanity checks on entry/exit VMCS control pairs
in anticipation of adding sanity checks for secondary exit controls (the
primary field is out of bits).
x86 (AMD):
* Ensure the PSP driver is initialized when both the PSP and KVM modules are
built-in (the initcall framework doesn't handle dependencies).
* Use long-term pins when registering encrypted memory regions, so that the
pages are migrated out of MIGRATE_CMA/ZONE_MOVABLE and don't lead to
excessive fragmentation.
* Add macros and helpers for setting GHCB return/error codes.
* Add support for Idle HLT interception, which elides interception if the vCPU
has a pending, unmasked virtual IRQ when HLT is executed.
* Fix a bug in INVPCID emulation where KVM fails to check for a non-canonical
address.
* Don't attempt VMRUN for SEV-ES+ guests if the vCPU's VMSA is invalid, e.g.
because the vCPU was "destroyed" via SNP's AP Creation hypercall.
* Reject SNP AP Creation if the requested SEV features for the vCPU don't
match the VM's configured set of features.
Selftests:
* Fix again the Intel PMU counters test; add a data load and do CLFLUSH{OPT} on the data
instead of executing code. The theory is that modern Intel CPUs have
learned new code prefetching tricks that bypass the PMU counters.
* Fix a flaw in the Intel PMU counters test where it asserts that an event is
counting correctly without actually knowing what the event counts on the
underlying hardware.
* Fix a variety of flaws, bugs, and false failures/passes dirty_log_test, and
improve its coverage by collecting all dirty entries on each iteration.
* Fix a few minor bugs related to handling of stats FDs.
* Add infrastructure to make vCPU and VM stats FDs available to tests by
default (open the FDs during VM/vCPU creation).
* Relax an assertion on the number of HLT exits in the xAPIC IPI test when
running on a CPU that supports AMD's Idle HLT (which elides interception of
HLT if a virtual IRQ is pending and unmasked).
USB-serial update for 6.15-rc1 Here's a single USB-serial cleanup for 6.15-rc1 that's been sitting in linux-next for a few weeks without any reported issues.
Hi Arnd, Thanks Christophe FSL SOC Changes for 6.15: - irqdomain cleanups from Jiry - Add Ioana as Maintainer of fsl-mc bus and remove Laurentiu and Stuart - Remove deadcode from fsl-mc bus
please consider pulling the following gfs2 changes for 6.15. Thanks, Andreas gfs2 changes - Fix two bugs related to locking request cancelation (locking request being retried instead of canceled; canceling the wrong locking request). - Prevent a race between inode creation and deferred delete analogous to commit ffd1cf0443a2 from 6.13. This now allows to further simplify gfs2_evict_inode() without introducing mysterious problems. - When in inode delete should be verified / retried "later" but that isn't possible, skip the delete instead of carrying it out immediately. This broke in 6.13. - More folio conversions from Matthew Wilcox (plus a fix from Dan Carpenter). - Various minor fixes and cleanups.

please pull the latest slab updates from: There's a small conflict with the rcu tree: https://lore.kernel.org/all/20250212150941.5e4fa1c9@canb.auug.org.au/ Thanks, Vlastimil * Move the TINY_RCU kvfree_rcu() implementation from RCU to SLAB subsystem and cleanup its integration (Vlastimil Babka) Following the move of the TREE_RCU batching kvfree_rcu() implementation in 6.14, move also the simpler TINY_RCU variant. Refactor the #ifdef guards so that the simple implementation is also used with SLUB_TINY. Remove the need for RCU to recognize fake callback function pointers (__is_kvfree_rcu_offset()) when handling call_rcu() by implementing a callback that calculates the object's address from the embedded rcu_head address without knowing its offset. * Improve kmalloc cache randomization in kvmalloc (GONG Ruiqi) Due to an extra layer of function call, all kvmalloc() allocations used the same set of random caches. Thanks to moving the kvmalloc() implementation to slub.c, this is improved and randomization now works for kvmalloc. * Various improvements to debugging, testing and other cleanups (Hyesoo Yu, Lilith Gkini, Uladzislau Rezki, Matthew Wilcox, Kevin Brodsky, Ye Bin)

LoongArch KVM changes for v6.15 1. Remove unnecessary header include path. 2. Remove PGD saving during VM context switch. 3. Add perf events support for guest VM.
There are two conflicts between the PV clock pull request and the Xen
pull request.
1. The Xen branch moves Xen TSC leaf updates to CPUID emulation, and the PV
clock branch renames the fields in kvm_vcpu_arch that are used to update
the Xen leafs. After the dust settles, kvm_cpuid() should look like:
} else if (IS_ENABLED(CONFIG_KVM_XEN) &&
kvm_xen_is_tsc_leaf(vcpu, function)) {
/*
* Update guest TSC frequency information if necessary.
* Ignore failures, there is no sane value that can be
* provided if KVM can't get the TSC frequency.
*/
if (kvm_check_request(KVM_REQ_CLOCK_UPDATE, vcpu))
kvm_guest_time_update(vcpu);
if (index == 1) {
*ecx = vcpu->arch.pvclock_tsc_mul;
*edx = vcpu->arch.pvclock_tsc_shift;
} else if (index == 2) {
*eax = vcpu->arch.hw_tsc_khz;
}
}
2. The Xen branch moves and renames xen_hvm_config so that its xen.hvm_config,
while PV clock branch shuffles use of xen_hvm_config/xen.hvm_config flags.
The resulting code in kvm_guest_time_update() should look like:
#ifdef CONFIG_KVM_XEN
/*
* For Xen guests we may need to override PVCLOCK_TSC_STABLE_BIT as unless
* explicitly told to use TSC as its clocksource Xen will not set this bit.
* This default behaviour led to bugs in some guest kernels which cause
* problems if they observe PVCLOCK_TSC_STABLE_BIT in the pvclock flags.
*
* Note! Clear TSC_STABLE only for Xen clocks, i.e. the order matters!
*/
if (ka->xen.hvm_config.flags & KVM_XEN_HVM_CONFIG_PVCLOCK_TSC_UNSTABLE)
hv_clock.flags &= ~PVCLOCK_TSC_STABLE_BIT;
if (vcpu->xen.vcpu_info_cache.active)
kvm_setup_guest_pvclock(&hv_clock, v, &vcpu->xen.vcpu_info_cache,
offsetof(struct compat_vcpu_info, time));
if (vcpu->xen.vcpu_time_info_cache.active)
kvm_setup_guest_pvclock(&hv_clock, v, &vcpu->xen.vcpu_time_info_cache, 0);

to coordinate the move of selftests out of lib/ and into lib/tests/. A separate tree was used for this to keep the paths sane with all the work in the same place. Doing this across multiple trees was going to be very difficult, so any on-going updates were collected here to try to avoid merge conflicts. I think only one small conflict remains, just today, detailed here: https://lore.kernel.org/linux-next/20250317213953.01ca90e9@canb.auug.org.au/ sfr's resolution looks correct.

1-Wire bus drivers for v6.14 1. W1 UART: Fix theoretical NULL pointer dereference in probe due to serdev ops being set too late. That's said such scenario is unlikely to happen as serdev read would need to happen before writing anything. 2. W1 therm: Simplify with HWMON_CHANNEL_INFO.
Samsung pinctrl drivers changes for v6.15 1. Add pin controller drivers for newly usptreamed Samsung Exynos2200 and Exynos7870. 2. Correct filter configuration offset of some of Google GS101 SoC pin banks, which later is supposed to be used during system suspend/resume.
Memory controller drivers for v6.15 1. Minor cleanup in Nvidia Tegra20 EMC. 2. Extend support for Mediatek MT8192 to match recommended by vendor and improve VENC hardware behavior during stress testing.
Hi Miguel, This initial support allows for intrusive use of timers without allocating when starting a timer. We support `Pin<Box<T>>`, `Arc<T>`, `Pin<&T>` and `Pin<&mut T>` pointer types for working with these intrusive timers. We support at most one `HrTimer` field in a struct for use with this API. For now, the primary users will be the Rust null block driver, `rnull`, and the Rust kernel mode setting driver `rkvms`. I expect us to add more features to the API as the demands from users grow. The PR also includes two changes for the core rust and rust/alloc subsytems that are dependencies of the hrtimer Rust API: `Arc::as_ptr` and `Box::into_pin`. The alloc change was Ack'd by Danilo. The commits were in linux-next since next-20250313. Rust hrtimer API for v6.15 Introduce Rust support for the `hrtimer` subsystem: - Add a way to use the `hrtimer` subsystem from Rust. Rust code can now set up intrusive timers without allocating when starting the timer. - Add support for `Pin<Box<_>>`, `Arc<_>`, `Pin<&_>` and `Pin<&mut _>` as pointer types for use with timer callbacks. - Add support for setting clock source and timer mode. `kernel` crate: - Add `Arc::as_ptr` for converting an `Arc` to a raw pointer. This is a dependency for the `hrtimer` API. - Add `Box::into_pin` for converting a `Box<_>` into a `Pin<Box<_>>` to align with Rust `alloc`. This is a dependency for the `hrtimer` API.

Samsung SoC drivers for v6.15 1. Add support for Exynos USI v1 serial engines. Drivers already supported newer IP blocks - USI v2 - present in Exynos850 and newer. A bit older ARM64 designs, like Exynos8895 use older USI v1 block. 2. Add Exynos ACPM (Alive Clock and Power Manager) protocol driver for Google GS101 SoC. ACPM protocol allows communication between the power management firmware and other embedded processors. 3. Exynos2200: Add PMU, ChipID and SYSREG Devicetree bindings. 4. Exynos7870: Add PMU and ChipID Devicetree bindings. 5. Various cleanups.
Hi, New clk drivers for Samsung SoC. This pull includes drivers which you commented later and pointed out few issues. Pointed issues are in all Samsung clk drivers and the ones here just copy existing patterns: 1. Headers: I fixed it for new and existing drivers and this pull request includes the fixes. 2. device_get_match_data(): I still wait for contributors response. If they do not respond, I will fix it for next cycle. 3. refdata and platform_driver_probe: I tried fixing it, but incomplete and need to investigate more. Best regards, Krzysztof Samsung SoC clock drivers changes for 6.15 1. Exynos990: Add support for the PERIS clock controller in existing driver. 2. Exynos2200: Add new driver for several clock controllers (Alive, CMGP, HSI, PERIC/PERIS, TOP, UFS and VFS). 3. Exynos7870: Add new driver for several clock controllers (Alive, MIF, DISP AUD, FSYS, G3D, ISP, MFC and PERI). 4. Correct undefined behavior / runtime array bounds check of flexible array member (last 'hws' element in 'struct clk_hw_onecell_data'). The code was logically correct for normal case, but not for the clang/GCC runtime bounds checking of flexible array member. 5. Few cleanups: spelling, header inclusions.
