workqueue: Refactor worker ID formatting and make wq_worker_comm() use full ID string
Currently, worker ID formatting is open coded in create_worker(), init_rescuer() and worker_thread() (for %WORKER_DIE case). The formatted ID is saved into task->comm and wq_worker_comm() uses it as the base name to append extra information to when generating the name to be shown to userspace. However, TASK_COMM_LEN is only 16 leading to badly truncated names for rescuers. For example, the rescuer for the inet_frag_wq workqueue becomes: $ ps -ef | grep '[k]worker/R-inet' root 483 2 0 Apr26 ? 00:00:00 [kworker/R-inet_] Even for non-rescue workers, it's easy to run over 15 characters on moderately large machines. Fit it by consolidating worker ID formatting into a new helper format_worker_id() and calling it from wq_worker_comm() to obtain the untruncated worker ID string. $ ps -ef | grep '[k]worker/R-inet' root 60 2 0 12:10 ? 00:00:00 [kworker/R-inet_frag_wq] Signed-off-by: Tejun Heo <tj@kernel.org> Reported-and-tested-by: Jan Engelhardt <jengelh@inai.de> Suggested-by: Linus Torvalds <torvalds@linux-foundation.org> |

asm-generic cleanups for 6.10
These are a few cross-architecture cleanup patches:
- Thomas Zimmermann works on separating fbdev support from the asm/video.h
contents that may be used by either the old fbdev drivers or the
newer drm display code.
- Thorsten Blum contributes cleanups for the generic bitops code
and asm-generic/bug.h
- I remove the orphaned include/asm-generic/page.h header that used to
included by long-removed mmu-less architectures.

soc: devicetree updates for v6.10, part 2
This is a follow-up to an earlier pull request for device tree changes,
as three platform maintainers sent their contents too late to be included
in the main set, but had not caused any further problems since then:
- The Amlogic platform now containts support for two new SoC types,
the A4 and A5 chips for audio applications. Both come with a
reference board, and one more dts file gets addded for the
combination of the MNT Reform Laptop with the BPI-CM4 CPU
module
- The ASpeed platform adds support for six addititional server
platforms that use ast2500 or ast2600 as their BMC, while
another one gets removed.
- The RISC-V platforms from Microchip, Starfive and and T-HEAD
get additional features for existing hardware, plus the
addition of the Milk-V Mars based on the StarFive VisionFive v2
board.

f2fs update for 6.10-rc1
In this round, we've tried to address some performance issues on zoned storage
such as direct IO and write_hints. In addition, we've migrated some IO paths
using folio. Meanwhile, there are multiple bug fixes in the compression paths,
sanity check conditions, and error handlers.
Enhancement:
- allow direct io of pinned files for zoned storage
- assign the write hint per stream by default
- convert read paths and test_writeback to folio
- avoid allocating WARM_DATA segment for direct IO
Bug fix:
- fix false alarm on invalid block address
- fix to add missing iput() in gc_data_segment()
- fix to release node block count in error path of f2fs_new_node_page()
- compress: don't allow unaligned truncation on released compress inode
- compress: fix to cover {reserve,release}_compress_blocks() w/ cp_rwsem lock
- compress: fix error path of inc_valid_block_count()
- compress: fix to update i_compr_blocks correctly
- fix block migration when section is not aligned to pow2
- don't trigger OPU on pinfile for direct IO
- fix to do sanity check on i_xattr_nid in sanity_check_inode()
- write missing last sum blk of file pinning section
- clear writeback when compression failed
- fix to adjust appropirate defragment pg_end
As usual, there are several minor code clean-ups, and fixes to manage missing
corner cases in the error paths.

New code for 6.10:
* Introduce Parent Pointer extended attribute for inodes.
* Online Repair
- Implement atomic file content exchanges i.e. exchange ranges of bytes
between two files atomically.
- Create temporary files to repair file-based metadata. This uses atomic
file content exchange facility to swap file fork mappings between the
temporary file and the metadata inode.
- Allow callers of directory/xattr code to set an explicit owner number to
be written into the header fields of any new blocks that are created.
This is required to avoid walking every block of the new structure and
modify their ownership during online repair.
- Repair
- Extended attributes
- Inode unlinked state
- Directories
- Symbolic links
- AGI's unlinked inode list.
- Parent pointers.
- Move Orphan files to lost and found directory.
- Fixes for Inode repair functionality.
- Introduce a new sub-AG FITRIM implementation to reduce the duration for
which the AGF lock is held.
- Updates for the design documentation.
- Use Parent Pointers to assist in checking directories, parent pointers,
extended attributes, and link counts.
* Bring back delalloc support for realtime devices which have an extent size
that is equal to filesystem's block size.

Pull xfs updates from Chandan Babu:
"Online repair feature continues to be expanded. Also, we now support
delayed allocation for realtime devices which have an extent size that
is equal to filesystem's block size.
New code:
- Introduce Parent Pointer extended attribute for inodes
- Bring back delalloc support for realtime devices which have an
extent size that is equal to filesystem's block size
- Improve performance of log incompat feature handling
Online Repair:
- Implement atomic file content exchanges i.e. exchange ranges of
bytes between two files atomically
- Create temporary files to repair file-based metadata. This uses
atomic file content exchange facility to swap file fork mappings
between the temporary file and the metadata inode
- Allow callers of directory/xattr code to set an explicit owner
number to be written into the header fields of any new blocks that
are created. This is required to avoid walking every block of the
new structure and modify their ownership during online repair
- Repair more data structures:
- Extended attributes
- Inode unlinked state
- Directories
- Symbolic links
- AGI's unlinked inode list
- Parent pointers
- Move Orphan files to lost and found directory
- Fixes for Inode repair functionality
- Introduce a new sub-AG FITRIM implementation to reduce the duration
for which the AGF lock is held
- Updates for the design documentation
- Use Parent Pointers to assist in checking directories, parent
pointers, extended attributes, and link counts
Fixes:
- Prevent userspace from reading invalid file data due to incorrect.

bcachefs changes for 6.10-rc1
- More safety fixes, primarily found by syzbot - Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is primarily for testing fsck/recovery in dry run mode, so it shouldn't change anything besides disabling writes and holding dirty metadata in memory. The idea here was to reduce the amount of activity if we can't write anything out, so that bringing up a filesystem in "super ro" mode would be more lilkely to work for data recovery - but norecovery is the correct option for this. - btree_trans->locked; we now track whether a btree_trans has any btree nodes locked, and this is used for improved assertions related to trans_unlock() and trans_relock(). We'll also be using it for improving how we work with lockdep in the future: we don't want lockdep to be tracking individual btree node locks because we take too many for lockdep to track, and it's not necessary since we have a cycle detector. - Trigger improvements that are prep work for online fsck - BTREE_TRIGGER_check_repair; this regularizes how we do some repair work for extents that goes with running triggers in fsck, and fixes some subtle issues with transaction restarts there. - bch2_snapshot_equiv() has now been ripped out of fsck.c; snapshot equivalence classes are for when snapshot deletion leaves behind redundant snapshot nodes, but snapshot deletion now cleans this up right away, so the abstraction doesn't need to leak. - Improvements to how we resume writing to the journal in recovery. The code for picking the new place to write when reading the journal is greatly simplified and we also store the position in the superblock for when we don't read the journal; this means that we preserve more of the journal for list_journal debugging. - Improvements to sysfs btree_cache and btree_node_cache, for debugging memory reclaim. - We now detect when we've blocked for 10 seconds on the allocator in the write path and dump some useful info. - Safety fixes for devices references: this is a big series that changes almost all device lookups to properly check if the device exists and take a reference to it. Previously we assumed that if a bkey exists that references a device then the device must exist, and this was enforced in .invalid methods, but this was incorrect because it meant device removal relied on accounting being correct to not leave keys pointing to invalid devices, and that's not something we can assume. Getting the "pointer to invalid device" checks out of our .invalid() methods fixes some long standing device removal bugs; the only outstanding bug with device removal now is a race between the discard path and deleting alloc info, which should be easily fixed. - The allocator now prefers not to expand the new member_info.btree_allocated bitmap, meaning if repair ever requires scanning for btree nodes (because of a corrupt interior nodes) we won't have to scan the whole device(s). - New coding style document, which among other things talks about the correct usage of assertions -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKnAFLkS8Qha+jvQrE6szbY3KbnYFAmZKJQgACgkQE6szbY3K bnZETg//SU9H0OHnBSMB/cteF6PKo9QR+dhT+3n+gWTxl0o/egbGTqwbzVqGtd2f J6II1BsDk8VoTOb/gFfLRShlmJfnj2jpRThU265faR/7LQYeSaqndDPkjOpTayAD Nj/DJyiSUTL753rZh3yUhOpOIHf7iapH6wuaZCPfhdfk+yvZNW8iz07JHjHLKRp8 I2cFH0r6kN916NdRkt9oDCz68WouT8eWTqwcKra04XsLEZjNJHxLpKMq4M8UdPc7 YynJPVt+aP8+VduGIq6pV8Co3afCP2oUywo11JpRmvLsw4tex/59wxOYtpMfgn6k 4H+9WqiBwkbmnLDrfFHWRameS6F/7+GRAOVuz9nkmfk61UPU15gLjSRffqZ6u2YC 7vbrXgebId/sZXtBpQd83RMMX52BnEJah0upNJ54IsSqfDYkU9lwl6CEyYpcX1hf YNBGBTbspZztc3AB13b3ow421FMhaySUg0FDmntMR9O8Z6/BXk7Ykc7b8DPEfrFs W6JY7q+ARBxr+EgFcV74fvMCf7NJTAhyv80AKryo7NFU2JZOyyaTxcTGSnolX4Mi lyHiOgicmOX+vy3vbC1dZoDcmIDJ4Uc0vixYcpKiZqxlR8XJ+wpevC50TEhxrcW+ ZO4SloQvgyjI34xu/gZgjRYb3BhXK3x+ougVFpRG8V8zQ/+ccWg= =MKrF -----END PGP SIGNATURE----- Merge tag 'bcachefs-2024-05-19' of https://evilpiepirate.org/git/bcachefs Pull bcachefs updates from Kent Overstreet: - More safety fixes, primarily found by syzbot - Run the upgrade/downgrade paths in nochnages mode.

kgdb patches for 6.10
Nine patches this cycle and they split into just three topics:
1. Adopt coccinelle's recommendation to adopt str_plural().
2. A set of seven patches to refactor kdb_read() to improve both code clarity
and it's discipline with respect to fixed size buffers. This isn't just a
refactor. Between them these also fix a cursor movement redraw problem and
two buffer overflows (one latent and one real, albeit difficult to
tickle).
3. Fix an NMI-safety problem when enqueuing kdb's keyboard reset code.
I wrote eight of the nine patches in this collection so many thanks to Doug
Anderson for the reviews. The changes that affects drivers/tty/serial is
acked by Greg KH.

The usual shower of singleton fixes and minor series all over MM,
documented (hopefully adequately) in the respective changelogs. Notable
series include:
- Lucas Stach has provided some page-mapping
cleanup/consolidation/maintainability work in the series "mm/treewide:
Remove pXd_huge() API".
- In the series "Allow migrate on protnone reference with
MPOL_PREFERRED_MANY policy", Donet Tom has optimized mempolicy's
MPOL_PREFERRED_MANY mode, yielding almost doubled performance in one
test.
- In their series "Memory allocation profiling" Kent Overstreet and
Suren Baghdasaryan have contributed a means of determining (via
/proc/allocinfo) whereabouts in the kernel memory is being allocated:
number of calls and amount of memory.
- Matthew Wilcox has provided the series "Various significant MM
patches" which does a number of rather unrelated things, but in largely
similar code sites.
- In his series "mm: page_alloc: freelist migratetype hygiene" Johannes
Weiner has fixed the page allocator's handling of migratetype requests,
with resulting improvements in compaction efficiency.
- In the series "make the hugetlb migration strategy consistent" Baolin
Wang has fixed a hugetlb migration issue, which should improve hugetlb
allocation reliability.
- Liu Shixin has hit an I/O meltdown caused by readahead in a
memory-tight memcg. Addressed in the series "Fix I/O high when memory
almost met memcg limit".
- In the series "mm/filemap: optimize folio adding and splitting" Kairui
Song has optimized pagecache insertion, yielding ~10% performance
improvement in one test.
- Baoquan He has cleaned up and consolidated the early zone
initialization code in the series "mm/mm_init.c: refactor
free_area_init_core()".
- Baoquan has also redone some MM initializatio code in the series
"mm/init: minor clean up and improvement".
- MM helper cleanups from Christoph Hellwig in his series "remove
follow_pfn".
- More cleanups from Matthew Wilcox in the series "Various page->flags
cleanups".
- Vlastimil Babka has contributed maintainability improvements in the
series "memcg_kmem hooks refactoring".
- More folio conversions and cleanups in Matthew Wilcox's series
"Convert huge_zero_page to huge_zero_folio"
"khugepaged folio conversions"
"Remove page_idle and page_young wrappers"
"Use folio APIs in procfs"
"Clean up __folio_put()"
"Some cleanups for memory-failure"
"Remove page_mapping()"
"More folio compat code removal"
- David Hildenbrand chipped in with "fs/proc/task_mmu: convert hugetlb
functions to work on folis".
- Code consolidation and cleanup work related to GUP's handling of
hugetlbs in Peter Xu's series "mm/gup: Unify hugetlb, part 2".
- Rick Edgecombe has developed some fixes to stack guard gaps in the
series "Cover a guard gap corner case".
- Jinjiang Tu has fixed KSM's behaviour after a fork+exec in the series
"mm/ksm: fix ksm exec support for prctl".
- Baolin Wang has implemented NUMA balancing for multi-size THPs. This
is a simple first-cut implementation for now. The series is "support
multi-size THP numa balancing".
- Cleanups to vma handling helper functions from Matthew Wilcox in the
series "Unify vma_address and vma_pgoff_address".
- Some selftests maintenance work from Dev Jain in the series
"selftests/mm: mremap_test: Optimizations and style fixes".
- Improvements to the swapping of multi-size THPs from Ryan Roberts in
the series "Swap-out mTHP without splitting".
- Kefeng Wang has significantly optimized the handling of arm64's
permission page faults in the series
"arch/mm/fault: accelerate pagefault when badaccess"
"mm: remove arch's private VM_FAULT_BADMAP/BADACCESS"
- GUP cleanups from David Hildenbrand in "mm/gup: consistently call it
GUP-fast".
- hugetlb fault code cleanups from Vishal Moola in "Hugetlb fault path to
use struct vm_fault".
- selftests build fixes from John Hubbard in the series "Fix
selftests/mm build without requiring "make headers"".
- Memory tiering fixes/improvements from Ho-Ren (Jack) Chuang in the
series "Improved Memory Tier Creation for CPUless NUMA Nodes". Fixes
the initialization code so that migration between different memory types
works as intended.
- David Hildenbrand has improved follow_pte() and fixed an errant driver
in the series "mm: follow_pte() improvements and acrn follow_pte()
fixes".
- David also did some cleanup work on large folio mapcounts in his
series "mm: mapcount for large folios + page_mapcount() cleanups".
- Folio conversions in KSM in Alex Shi's series "transfer page to folio
in KSM".
- Barry Song has added some sysfs stats for monitoring multi-size THP's
in the series "mm: add per-order mTHP alloc and swpout counters".
- Some zswap cleanups from Yosry Ahmed in the series "zswap same-filled
and limit checking cleanups".
- Matthew Wilcox has been looking at buffer_head code and found the
documentation to be lacking. The series is "Improve buffer head
documentation".

NFSD 6.10 Release Notes
This is a light release containing mostly optimizations, code clean-
ups, and minor bug fixes. This development cycle has focused on non-
upstream kernel work:
1. Continuing to build upstream CI for NFSD, based on kdevops
2. Backporting NFSD filecache-related fixes to selected LTS kernels
One notable new feature in v6.10 NFSD is the addition of a new

Pull nfsd updates from Chuck Lever:
"This is a light release containing mostly optimizations, code clean-
ups, and minor bug fixes. This development cycle has focused on non-
upstream kernel work:
1. Continuing to build upstream CI for NFSD, based on kdevops
2. Backporting NFSD filecache-related fixes to selected LTS kernels
One notable new feature in v6.10 NFSD is the addition of a new netlink
protocol dedicated to configuring NFSD. A new user space tool,
nfsdctl, is to be added to nfs-utils. Lots more to come here.
As always I am very grateful to NFSD contributors, reviewers, testers,

"Aside from the usual things this has an arch update for
__iowrite64_copy() used by the RDMA drivers.
This API was intended to generate large 64 byte MemWr TLPs on PCI.
These days most processors had done this by just repeating writel() in
a loop. S390 and some new ARM64 designs require a special helper to
get this to generate.

I'm actually surprised this time. There aren't any new Qualcomm SoC clk
drivers. And there's zero diff in the core clk framework. Instead we have new
clk drivers for STM and Sophgo, with Samsung^WGoogle in third for the diffstat
because they introduced HSI0 and HSI2 clk drivers for Google's GS101 SoC (high
speed interface things like PCIe, UFS, and MMC). Beyond those big diffs there's
the usual updates to various clk drivers for incorrect parent descriptions or
mising MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super
interesting here.
New Drivers:
- STM32MP257 SoC clk driver
- Airoha EN7581 SoC clk driver
- Sophgo CV1800B, CV1812H and SG2000 SoC clk driver
- Loongson-2k0500 and Loongson-2k2000 SoC clk driver
- Add HSI0 and HSI2 clock controllers for Google GS101
- Add i.MX95 BLK CTL clock driver
Updates:
- Allocate clk_ops dynamically for SCMI clk driver
- Add support in qcom RCG and RCG2 for multiple configurations for the same frequency
- Use above support for IPQ8074 NSS port 5 and 6 clocks to resolve issues
- Fix the Qualcomm APSS IPQ5018 PLL to fix boot failures of some boards
- Cleanups and fixes for Qualcomm Stromer PLLs
- Reduce max CPU frequency on Qualcomm APSS IPQ5018
- Fix Kconfig dependencies of Qualcomm SM8650 GPU and SC8280XP camera
clk drivers
- Make Qualcomm MSM8998 Venus clocks functional
- Cleanup downstream remnants related to DisplayPort across Qualcomm
SM8450, SM6350, SM8550, and SM8650
- Reuse the Huayra APSS register map on Qualcomm MSM8996 CBF PLL
- Use a specific Qualcomm QCS404 compatible for the otherwise generic
HFPLL
- Remove Qualcomm SM8150 CPUSS AHB clk as it is unused
- Remove an unused field in the Qualcomm RPM clk driver
- Add missing MODULE_DEVICE_TABLE to Qualcomm MSM8917 and MSM8953
global clock controller drivers
- Allow choice of manual or firmware-driven control over PLLs, needed
to fully implement CPU clock controllers on Exynos850
- Correct PLL clock IDs on ExynosAutov9
- Propagate certain clock rates to allow setting proper SPI clock
rates on Google GS101
- Mark certain Google GS101 clocks critical
- Convert old S3C64xx clock controller bindings to DT schema
- Add new PLL rate and missing mux on Rockchip rk3568
- Add missing reset line on Rockchip rk3588
- Removal of an unused field in struct rockchip_mmc_clock
- Amlogic s4/a1: add regmap maximum register for proper debugfs dump
- Amlogic s4: add MODULE_DEVICE_TABLE() on pll and periph controllers
- Amlogic pll driver: print clock name on lock error to help debug
- Amlogic vclk: finish dsi clock path support
- Amlogic license: fix occurence "GPL v2" as reported by checkpatch
- Add PM runtime support to i.MX8MP Audiomix
- Add DT schema for i.MX95 Display Master Block Control
- Convert to platform remove callback returning void for i.MX8MP
Audiomix
- Add SPI (MSIOF) and external interrupt (INTC-EX) clocks on Renesas R-Car V4M
- Add interrupt controller (PLIC) clock and reset on Renesas RZ/Five
- Prepare power domain support for Renesas RZ/G2L family members, and add
actual support on Renesas RZ/G3S SoC
- Add thermal, serial (SCIF), and timer (CMT/TMU) clocks on Renesas R-Car V4M
- Add additional constraints to Allwinner A64 PLL MIPI clock
- Fix autoloading sunxi-ng clocks when build as a module

Specific for timerlat:
- Improves the output of timerlat top by adding a missing \n,
and by avoiding printing color-formatting characters where
they are translated to regular characters.
- Improves timerlat auto-analysis output by replacing '\t'
with spaces to avoid copy-and-paste issues when reporting
problems.
- For timerlat, make the user-space (-u) option the default,
as it is the most complete test. Add a -k option to use
the in-kernel workload.
- On timerlat top and hist, add a summary with the overall
results. For instance, the minimum value for all CPUs,
the overall average and the maximum value from all CPUs.
- timerlat hist was printing initial values (i.e., 0 as max,
and ~0 as min) if the trace stopped before the first Ret-User
event. This problem was fixed by printing the " - "
no value string to the output if that was the case.
For all RTLA tools:
- Add a --warm-up <seconds> option, allowing the workload to
run for <seconds> before starting to collect results.
- Add a --trace-buffer-size option, allowing the user to set
the tracing buffer size for -t option. This option is mainly
useful for reducing the trace file. Now rtla depends on
libtracefs >= 1.6.
- Fix the -t [trace_file] parsing, now it does not require
the '=' before the option parameter, and better handles the
multiple ways a user can pass the trace_file.txt

user-event updates for v6.10:
- Minor update to the user_events interface The ABI of creating a user event states that the fields are separated by semicolons, and spaces should be ignored. But the parsing expected at least one space to be there (which was incorrect). Fix the reading of the string to handle fields separated by semicolons but no space between them. This does extend the API sightly as now "field;field" will now be parsed and not cause an error. But it should not cause any regressions as no logic should expect it to fail. Note, that the logic that parses the event fields to create the trace_event works with no spaces after the semi-colon. It is the logic that tests against existing events that is inconsistent. This causes registering an event without using spaces to succeed if it doesn't exist, but makes the same call that tries to register to the same event, but doesn't use spaces, fail. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZkZN1hQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qvCXAQDO8b2GeCuAMa2SW7PMFdpB2Tc2F5v4 WPBEKaLb0TU+7AEAwR0rCm22p9rpke754lcpZDz7xJNcyiyMkyXeJWCauQA= =PYwP -----END PGP SIGNATURE----- Merge tag 'trace-user-events-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing user-event updates from Steven Rostedt: - Minor update to the user_events interface The ABI of creating a user event states that the fields are separated by semicolons, and spaces should be ignored.

tracing ring buffer updates for v6.10:
- Add ring_buffer memory mappings The tracing ring buffer was created based on being mostly used with the splice system call. It is broken up into page ordered sub-buffers and the reader swaps a new sub-buffer with an existing sub-buffer that's part of the write buffer. It then has total access to the swapped out sub-buffer and can do copyless movements of the memory into other mediums (file system, network, etc). The buffer is great for passing around the ring buffer contents in the kernel, but is not so good for when the consumer is the user space task itself. A new interface is added that allows user space to memory map the ring buffer. It will get all the write sub-buffers as well as reader sub-buffer (that is not written to). It can send an ioctl to change which sub-buffer is the new reader sub-buffer. The ring buffer is read only to user space. It only needs to call the ioctl when it is finished with a sub-buffer and needs a new sub-buffer that the writer will not write over. A self test program was also created for testing and can be used as an example for the interface to user space. The libtracefs (external to the kernel) also has code that interacts with this, although it is disabled until the interface is in a official release.

The tracing ring buffer was created based on being mostly used with the splice system call. It is broken up into page ordered sub-buffers and the reader swaps a new sub-buffer with an existing sub-buffer that's part of the write buffer. It then has total access to the swapped out sub-buffer and can do copyless movements of the memory into other mediums (file system, network, etc). The buffer is great for passing around the ring buffer contents in the kernel, but is not so good for when the consumer is the user space task itself. A new interface is added that allows user space to memory map the ring buffer. It will get all the write sub-buffers as well as reader sub-buffer (that is not written to). It can send an ioctl to change which sub-buffer is the new reader sub-buffer. The ring buffer is read only to user space. It only needs to call the ioctl when it is finished with a sub-buffer and needs a new sub-buffer that the writer will not write over. A self test program was also created for testing and can be used as an example for the interface to user space. The libtracefs (external to the kernel) also has code that interacts with this, although it is disabled until the interface is in a official release.

tracing cleanups for v6.10:
- Removed unused ftrace_direct_funcs variables - Fix a possible NULL pointer dereference race in eventfs - Update do_div() usage in trace event benchmark test - Speedup direct function registration with asynchronous RCU callback. The synchronization was done in the registration code and this caused delays when registering direct callbacks. Move the freeing to a call_rcu() that will prevent delaying of the registering. - Replace simple_strtoul() usage with kstrtoul() -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZkYrphQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qnNbAP0TCG5dLbHlcUtXFCG3AdOufOteyJZ4 efbRjFq0QY/RvQD7Bh1BNLSBsG0ptKPC7ch377A55xsgxZTr0mEarVTOQwg= =GKXv -----END PGP SIGNATURE----- Merge tag 'trace-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Remove unused ftrace_direct_funcs variables - Fix a possible NULL pointer dereference race in eventfs - Update do_div() usage in trace event benchmark test - Speedup direct function registration with asynchronous RCU callback.
