Merge tag 'f2fs-for-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs update from Jaegeuk Kim:
"In this series, we've some progress to support Zoned block device
regarding to the power-cut recovery flow and enabling
checkpoint=disable feature which is essential for Android OTA.
Other than that, some patches touched sysfs entries and tracepoints
which are minor, while several bug fixes on error handlers and
compression flows are good to improve the overall stability.
Enhancements:
- enable checkpoint=disable for zoned block device
- sysfs entries such as discard status, discard_io_aware, dir_level
- tracepoints such as f2fs_vm_page_mkwrite(), f2fs_rename(),
f2fs_new_inode()
- use shared inode lock during f2fs_fiemap() and f2fs_seek_block()
Bug fixes:
- address some power-cut recovery issues on zoned block device
- handle errors and logics on do_garbage_collect(),
f2fs_reserve_new_block(), f2fs_move_file_range(),
f2fs_recover_xattr_data()
- don't set FI_PREALLOCATED_ALL for partial write
- fix to update iostat correctly in f2fs_filemap_fault()
- fix to wait on block writeback for post_read case
- fix to tag gcing flag on page during block migration
- restrict max filesize for 16K f2fs
- fix to avoid dirent corruption
- explicitly null-terminate the xattr list
There are also several clean-up patches to remove dead codes and
better readability"

Pull documentation update from Jonathan Corbet:
"Another moderately busy cycle for documentation, including:
- The minimum Sphinx requirement has been raised to 2.4.4, following
a warning that was added in 6.2
- Some reworking of the Documentation/process front page to,
hopefully, make it more useful
- Various kernel-doc tweaks to, for example, make it deal properly
with __counted_by annotations
- We have also restored a warning for documentation of nonexistent
structure members that disappeared a while back. That had the
delightful consequence of adding some 600 warnings to the docs
build. A sustained effort by Randy, Vegard, and myself has
addressed almost all of those, bringing the documentation back into
sync with the code. The fixes are going through the appropriate
maintainer trees
- Various improvements to the HTML rendered docs, including automatic
links to Git revisions and a nice new pulldown to make translations
easy to access
- Speaking of translations, more of those for Spanish and Chinese

Merge tag 'net-next-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"The most interesting thing is probably the networking structs
reorganization and a significant amount of changes is around
self-tests.
Core & protocols:
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up build
time warnings to safeguard against future header changes
This improves TCP performances with many concurrent connections up
to 40%
- Add page-pool netlink-based introspection, exposing the memory
usage and recycling stats. This helps indentify bad PP users and
possible leaks
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set. This
lowers the time taken by connect() for hosts having many active
connections to the same destination
- Refactor the TCP bind conflict code, shrinking related socket
structs
- Refactor TCP SYN-Cookie handling, as a preparation step to allow
arbitrary SYN-Cookie processing via eBPF
- Tune optmem_max for 0-copy usage, increasing the default value to
128KB and namespecifying it
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations
- Reduce extension header parsing overhead at GRO time
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries
- Reorder nftables struct members, to keep data accessed by the
datapath first
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex)
- More data-race annotations
- Extend the diag interface to dump TCP bound-only sockets
- Conditional notification of events for TC qdisc class and actions
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID
- Implement SMCv2.1 virtual ISM device support
- Add support for Batman-avd mulicast packet type
BPF:
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers.
This improves the verifier "instructions processed" metric from
single digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer
experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques
- Support uid/gid options when mounting bpffs
- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is
identified by its id
- Extend verifier to allow bpf_refcount_acquire() of a map value
field obtained via direct load which is a use-case needed in
sched_ext
- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter
- Support for VLAN tag in XDP hints
- Remove deprecated bpfilter kernel leftovers given the project is
developed in user-space (https://github.com/facebook/bpfilter)
Misc:
- Support for parellel TC self-tests execution
- Increase MPTCP self-tests coverage
- Updated the bridge documentation, including several so-far
undocumented features
- Convert all the net self-tests to run in unique netns, to avoid
random failures due to conflict and allow concurrent runs
- Add TCP-AO self-tests
- Add kunit tests for both cfg80211 and mac80211
- Autogenerate Netlink families documentation from YAML spec
- Add yml-gen support for fixed headers and recursive nests, the tool
can now generate user-space code for all genetlink families for
which we have specs
- A bunch of additional module descriptions fixes
- Catch incorrect freeing of pages belonging to a page pool
Driver API:
- Rust abstractions for network PHY drivers; do not cover yet the
full C API, but already allow implementing functional PHY drivers
in rust
- Introduce queue and NAPI support in the netdev Netlink interface,
allowing complete access to the device <> NAPIs <> queues
relationship
- Introduce notifications filtering for devlink to allow control
application scale to thousands of instances
- Improve PHY validation, requesting rate matching information for
each ethtool link mode supported by both the PHY and host
- Add support for ethtool symmetric-xor RSS hash
- ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
platform
- Expose pin fractional frequency offset value over new DPLL generic
netlink attribute
- Convert older drivers to platform remove callback returning void
- Add support for PHY package MMD read/write

Merge tag 'sysctl-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux
Pull sysctl updates from Luis Chamberlain:
"To help make the move of sysctls out of kernel/sysctl.c not incur a
size penalty sysctl has been changed to allow us to not require the
sentinel, the final empty element on the sysctl array. Joel Granados
has been doing all this work.
In the v6.6 kernel we got the major infrastructure changes required to
support this. For v6.7 we had all arch/ and drivers/ modified to
remove the sentinel. For v6.8-rc1 we get a few more updates for fs/
directory only.
The kernel/ directory is left but we'll save that for v6.9-rc1 as
those patches are still being reviewed. After that we then can expect
also the removal of the no longer needed check for procname == NULL.
Let us recap the purpose of this work:
- this helps reduce the overall build time size of the kernel and run
time memory consumed by the kernel by about ~64 bytes per array
- the extra 64-byte penalty is no longer inncurred now when we move
sysctls out from kernel/sysctl.c to their own files
Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to
see further work by Thomas Weißschuh with the constificatin of the
struct ctl_table.
Due to Joel Granados's work, and to help bring in new blood, I have
suggested for him to become a maintainer and he's accepted. So for
v6.9-rc1 I look forward to seeing him sent you a pull request for
further sysctl changes. This also removes Iurii Zaikin as a maintainer
as he has moved on to other projects and has had no time to help at
all"

Merge tag 'bcachefs-2024-01-10' of https://evilpiepirate.org/git/bcachefs
Pull bcachefs updates from Kent Overstreet:
- btree write buffer rewrite: instead of adding keys to the btree write
buffer at transaction commit time, we now journal them with a
different journal entry type and copy them from the journal to the
write buffer just prior to journal write.
This reduces the number of atomic operations on shared cachelines in
the transaction commit path and is a signicant performance
improvement on some workloads: multithreaded 4k random writes went
from ~650k iops to ~850k iops.
- Bring back optimistic spinning for six locks: the new implementation
doesn't use osq locks; instead we add to the lock waitlist as normal,
and then spin on the lock_acquired bit in the waitlist entry, _not_
the lock itself.
- New ioctls:
- BCH_IOCTL_DEV_USAGE_V2, which allows for new data types
- BCH_IOCTL_OFFLINE_FSCK, which runs the kernel implementation of
fsck but without mounting: useful for transparently using the
kernel version of fsck from 'bcachefs fsck' when the kernel
version is a better match for the on disk filesystem.
- BCH_IOCTL_ONLINE_FSCK: online fsck. Not all passes are supported
yet, but the passes that are supported are fully featured - errors
may be corrected as normal.
The new ioctls use the new 'thread_with_file' abstraction for kicking
off a kthread that's tied to a file descriptor returned to userspace
via the ioctl.
- btree_paths within a btree_trans are now dynamically growable,
instead of being limited to 64. This is important for the
check_directory_structure phase of fsck, and also fixes some issues
we were having with btree path overflow in the reflink btree.
- Trigger refactoring; prep work for the upcoming disk space accounting
rewrite
- Numerous bugfixes :)

ext4: fix inconsistent between segment fstrim and full fstrim
Suppose we issue two FITRIM ioctls for ranges [0,15] and [16,31] with mininum length of trimmed range set to 8 blocks. If we have say a range of blocks 10-22 free, this range will not be trimmed because it straddles the boundary of the two FITRIM ranges and neither part is big enough. This is a bit surprising to some users that call FITRIM on smaller ranges of blocks to limit impact on the system. Also XFS trims all free space extents that overlap with the specified range so we are inconsistent among filesystems. Let's change ext4_try_to_trim_range() to consider for trimming the whole free space extent that straddles the end of specified range, not just the part of it within the range.

ext4: fallback to complex scan if aligned scan doesn't work
Currently in case the goal length is a multiple of stripe size we use ext4_mb_scan_aligned() to find the stripe size aligned physical blocks. In case we are not able to find any, we again go back to calling ext4_mb_choose_next_group() to search for a different suitable block group. However, since the linear search always begins from the start, most of the times we end up with the same BG and the cycle continues. With large fliesystems, the CPU can be stuck in this loop for hours which can slow down the whole system. Hence, until we figure out a better way to continue the search (rather than starting from beginning) in ext4_mb_choose_next_group(), lets just fallback to ext4_mb_complex_scan_group() in case aligned scan fails, as it is much more likely to find the needed blocks.

ext4: allow for the last group to be marked as trimmed
The ext4 filesystem tracks the trim status of blocks at the group
level. When an entire group has been trimmed then it is marked as
such and subsequent trim invocations with the same minimum trim size
will not be attempted on that group unless it is marked as able to be
trimmed again such as when a block is freed.
Currently the last group can't be marked as trimmed due to incorrect
logic in ext4_last_grp_cluster(). ext4_last_grp_cluster() is supposed
to return the zero based index of the last cluster in a group. This is
then used by ext4_try_to_trim_range() to determine if the trim
operation spans the entire group and as such if the trim status of the
group should be recorded.
ext4_last_grp_cluster() takes a 0 based group index, thus the valid
values for grp are 0..(ext4_get_groups_count - 1). Any group index
less than (ext4_get_groups_count - 1) is not the last group and must
have EXT4_CLUSTERS_PER_GROUP(sb) clusters. For the last group we need
to calculate the number of clusters based on the number of blocks in
the group. Finally subtract 1 from the number of clusters as zero
based indexing is expected. Rearrange the function slightly to make
it clear what we are calculating and returning.
Reproducer:
// Create file system where the last group has fewer blocks than
// blocks per group
$ mkfs.ext4 -b 4096 -g 8192 /dev/nvme0n1 8191
$ mount /dev/nvme0n1 /mnt
Before Patch:
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group not marked as trimmed so second invocation still discards blocks
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
After Patch:
fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group marked as trimmed so second invocation DOESN'T discard any blocks
fstrim -v /mnt
/mnt: 0 B (0 bytes) trimmed

Pull afs updates from David Howells:
"The majority of the patches are aimed at fixing and improving the AFS
filesystem's rotation over server IP addresses, but there are also
some fixes from Oleg Nesterov for the use of read_seqbegin_or_lock().
- Fix fileserver probe handling so that the next round of probes
doesn't break ongoing server/address rotation by clearing all the
probe result tracking. This could occasionally cause the rotation
algorithm to drop straight through, give a 'successful' result
without actually emitting any RPC calls, leaving the reply buffer
in an undefined state.
Instead, detach the probe results into a separate struct and
allocate a new one each time we start probing and update the
pointer to it. Probes are also sent in order of address preference
to try and improve the chance that the preferred one will complete
first.
- Fix server rotation so that it uses configurable address
preferences across on the probes that have completed so far than
ranking them by RTT as the latter doesn't necessarily give the best
route. The preference list can be altered by writing into
/proc/net/afs/addr_prefs.
- Fix the handling of Read-Only (and Backup) volume callbacks as
there is one per volume, not one per file, so if someone performs a
command that, say, offlines the volume but doesn't change it, when
it comes back online we don't spam the server with a status fetch
for every vnode we're using. Instead, check the Creation timestamp
in the VolSync record when prompted by a callback break.
- Handle volume regression (ie. a RW volume being restored from a
backup) by scrubbing all cache data for that volume. This is
detected from the VolSync creation timestamp.
- Adjust abort handling and abort -> error mapping to match better
with what other AFS clients do.
- Fix offline and busy volume state handling as they only apply to
individual server instances and not entire volumes and the rotation
algorithm should go and look at other servers if available. Also
make it sleep briefly before each retry if all the volume instances
are unavailable"

Pull btrfs updates from David Sterba:
"There are no exciting changes for users, it's been mostly API
conversions and some fixes or refactoring.
The mount API conversion is a base for future improvements that would
come with VFS. Metadata processing has been converted to folios, not
yet enabling the large folios but it's one patch away once everything
gets tested enough.
Core changes:
- convert extent buffers to folios:
- direct API conversion where possible
- performance can drop by a few percent on metadata heavy
workloads, the folio sizes are not constant and the calculations
add up in the item helpers
- both regular and subpage modes
- data cannot be converted yet, we need to port that to iomap and
there are some other generic changes required
- convert mount to the new API, should not be user visible:
- options deprecated long time ago have been removed: inode_cache,
recovery
- the new logic that splits mount to two phases slightly changes
timing of device scanning for multi-device filesystems
- LSM options will now work (like for selinux)
- convert delayed nodes radix tree to xarray, preserving the
preload-like logic that still allows to allocate with GFP_NOFS
- more validation of sysfs value of scrub_speed_max
- refactor chunk map structure, reduce size and improve performance
- extent map refactoring, smaller data structures, improved
performance
- reduce size of struct extent_io_tree, embedded in several
structures
- temporary pages used for compression are cached and attached to a
shrinker, this may slightly improve performance
- in zoned mode, remove redirty extent buffer tracking, zeros are
written in case an out-of-order is detected and proper data are
written to the actual write pointer
- cleanups, refactoring, error message improvements, updated tests
- verify and update branch name or tag
- remove unwanted text"

ksmbd: free ppace array on error in parse_dacl
The ppace array is not freed if one of the init_acl_state() calls inside
parse_dacl() fails. At the moment the function may fail only due to the
memory allocation errors so it's highly unlikely in this case but
nevertheless a fix is needed.
Move ppace allocation after the init_acl_state() calls with proper error
handling.

Merge tag 'acpi-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki:
"From the new features standpoint, the most significant change here is
the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
device enumeration code that will allow MIPI cameras to be enumerated
through the platform firmware on systems using ACPI.
Also significant is the switch-over to threaded interrupt handlers for
the ACPI SCI and the dedicated EC interrupt (on systems where the
former is not used) which essentially allows all ACPI code to run with
local interrupts enabled. That should improve responsiveness
significantly on systems where multiple GPEs are enabled and the
handling of one SCI involves many I/O address space accesses which
previously had to be carried out in one go with disabled interrupts on
the local CPU.
Apart from the above, the ACPI thermal zone driver will use the
Thermal fast Sampling Period (_TFP) object if available, which should
allow temperature changes to be followed more accurately on some
systems, the ACPI Notify () handlers can run on all CPUs (not just on
CPU0), which should generally speed up the processing of events
signaled through the ACPI SCI, and the ACPI power button driver will
trigger wakeup key events via the input subsystem (on systems where it
is a system wakeup device)
In addition to that, there are the usual bunch of fixes and cleanups.
Specifics:
- Add CSI-2 and DisCo for Imaging support to the ACPI device
enumeration code (Sakari Ailus, Rafael J. Wysocki)
- Adjust the cpufreq thermal reduction algorithm in the ACPI
processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd
Bergmann)
- Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki)
- Switch over ACPI to using a threaded interrupt handler for the SCI
(Rafael J. Wysocki)
- Allow ACPI Notify () handlers to run on all CPUs and clean up the
ACPI interface for deferred events processing (Rafael J. Wysocki)
- Switch over the ACPI EC driver to using a threaded handler for the
dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki)
- Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock
to keep local interrupts on (Rafael J. Wysocki)
- Adjust the USB4 _OSC handshake to correctly handle cases in which
certain types of OS control are denied by the platform (Mika
Westerberg)
- Correct and clean up the generic function for parsing ACPI
data-only tables with array structure (Yuntao Wang)
- Modify acpi_dev_uid_match() to support different types of its
second argument and adjust its users accordingly (Raag Jadav)
- Clean up code related to acpi_evaluate_reference() and ACPI device
lists (Rafael J. Wysocki)
- Use generic ACPI helpers for evaluating trip point temperature
objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd
Bergmann)
- Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal
zone driver (Jeff Brasen)
- Modify the ACPI LPIT table handling code to avoid u32
multiplication overflows in state residency computations (Nikita
Kiryushin)
- Drop an unused helper function from the ACPI backlight (video)
driver and add a clarifying comment to it (Hans de Goede)
- Update the ACPI backlight driver to avoid using uninitialized
memory in some cases (Nikita Kiryushin)
- Add ACPI backlight quirk for the Colorful X15 AT 23 laptop (Yuluo
Qiu)
- Add support for vendor-defined error types to the ACPI APEI error
injection code (Avadhut Naik)
- Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous
memory failure events, so they are handled differently from the
asynchronous ones (Shuai Xue)
- Fix NULL pointer dereference check in the ACPI extlog driver
(Prarit Bhargava)
- Adjust the ACPI extlog driver to clear the Extended Error Log
status when RAS_CEC handled the error (Tony Luck)
- Add IRQ override quirks for some Infinity laptops and for TongFang
GMxXGxx (David McFarland, Hans de Goede)
- Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is
not the same as one of the real pxm values (Yuntao Wang)
- Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC)
driver so as to prevent miscalculation of the values in the clock
divider (Andy Shevchenko)
- Adjust comments in the ACPI watchdog driver to prevent kernel-doc
from complaining during documentation builds (Randy Dunlap)
- Make the ACPI button driver send wakeup key events to user space in
addition to power button events on systems that can be woken up by
the power button (Ken Xue)
- Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full
structure field (Dmitry Antipov)"

Merge tag 'lsm-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm
Pull security module updates from Paul Moore: - Add three new syscalls: lsm_list_modules(), lsm_get_self_attr(), and lsm_set_self_attr(). The first syscall simply lists the LSMs enabled, while the second and third get and set the current process' LSM attributes. Yes, these syscalls may provide similar functionality to what can be found under /proc or /sys, but they were designed to support multiple, simultaneaous (stacked) LSMs from the start as opposed to the current /proc based solutions which were created at a time when only one LSM was allowed to be active at a given time. We have spent considerable time discussing ways to extend the existing /proc interfaces to support multiple, simultaneaous LSMs and even our best ideas have been far too ugly to support as a kernel API; after +20 years in the kernel, I felt the LSM layer had established itself enough to justify a handful of syscalls. Support amongst the individual LSM developers has been nearly unanimous, with a single objection coming from Tetsuo (TOMOYO) as he is worried that the LSM_ID_XXX token concept will make it more difficult for out-of-tree LSMs to survive. Several members of the LSM community have demonstrated the ability for out-of-tree LSMs to continue to exist by picking high/unused LSM_ID values as well as pointing out that many kernel APIs rely on integer identifiers, e.g. syscalls (!), but unfortunately Tetsuo's objections remain. My personal opinion is that while I have no interest in penalizing out-of-tree LSMs, I'm not going to penalize in-tree development to support out-of-tree development, and I view this as a necessary step forward to support the push for expanded LSM stacking and reduce our reliance on /proc and /sys which has occassionally been problematic for some container users. Finally, we have included the linux-api folks on (all?) recent revisions of the patchset and addressed all of their concerns. - Add a new security_file_ioctl_compat() LSM hook to handle the 32-bit ioctls on 64-bit systems problem. This patch includes support for all of the existing LSMs which provide ioctl hooks, although it turns out only SELinux actually cares about the individual ioctls. It is worth noting that while Casey (Smack) and Tetsuo (TOMOYO) did not give explicit ACKs to this patch, they did both indicate they are okay with the changes. - Fix a potential memory leak in the CALIPSO code when IPv6 is disabled at boot. While it's good that we are fixing this, I doubt this is something users are seeing in the wild as you need to both disable IPv6 and then attempt to configure IPv6 labeled networking via NetLabel/CALIPSO; that just doesn't make much sense. Normally this would go through netdev, but Jakub asked me to take this patch and of all the trees I maintain, the LSM tree seemed like the best fit. - Update the LSM MAINTAINERS entry with additional information about our process docs, patchwork, bug reporting, etc. I also noticed that the Lockdown LSM is missing a dedicated MAINTAINERS entry so I've added that to the pull request. I've been working with one of the major Lockdown authors/contributors to see if they are willing to step up and assume a Lockdown maintainer role; hopefully that will happen soon, but in the meantime I'll continue to look after it. - Add a handful of mailmap entries for Serge Hallyn and myself. * tag 'lsm-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (27 commits) lsm: new security_file_ioctl_compat() hook lsm: Add a __counted_by() annotation to lsm_ctx.ctx calipso: fix memory leak in netlbl_calipso_add_pass() selftests: remove the LSM_ID_IMA check in lsm/lsm_list_modules_test MAINTAINERS: add an entry for the lockdown LSM MAINTAINERS: update the LSM entry mailmap: add entries for Serge Hallyn's dead accounts mailmap: update/replace my old email addresses lsm: mark the lsm_id variables are marked as static lsm: convert security_setselfattr() to use memdup_user() lsm: align based on pointer length in lsm_fill_user_ctx() lsm: consolidate buffer size handling into lsm_fill_user_ctx() lsm: correct error codes in security_getselfattr() lsm: cleanup the size counters in security_getselfattr() lsm: don't yet account for IMA in LSM_CONFIG_COUNT calculation lsm: drop LSM_ID_IMA LSM: selftests for Linux Security Module syscalls SELinux: Add selfattr hooks AppArmor: Add selfattr hooks Smack: implement setselfattr and getselfattr hooks ... |

'Add folio_zero_tail() and folio_fill_tail()'
'Make folio_start_writeback return void'
'Fix fault handler's handling of poisoned tail pages'
'Convert aops->error_remove_page to ->error_remove_folio'
'Finish two folio conversions'
'More swap folio conversions'
- Kefeng Wang has also contributed folio-related work in the series
'mm: cleanup and use more folio in page fault'
- Jim Cromie has improved the kmemleak reporting output in the series
'tweak kmemleak report format'.
- In the series 'stackdepot: allow evicting stack traces' Andrey
Konovalov to permits clients (in this case KASAN) to cause eviction
of no longer needed stack traces.
- Charan Teja Kalla has fixed some accounting issues in the page
allocator's atomic reserve calculations in the series 'mm:
page_alloc: fixes for high atomic reserve caluculations'.
- Dmitry Rokosov has added to the samples/ dorectory some sample code
for a userspace memcg event listener application. See the series
'samples: introduce cgroup events listeners'.
- Some mapletree maintanance work from Liam Howlett in the series
'maple_tree: iterator state changes'.
- Nhat Pham has improved zswap's approach to writeback in the series
'workload-specific and memory pressure-driven zswap writeback'.
- DAMON/DAMOS feature and maintenance work from SeongJae Park in the
series
'mm/damon: let users feed and tame/auto-tune DAMOS'
'selftests/damon: add Python-written DAMON functionality tests'

- Yosry Ahmed has improved memcg's stats flushing in the series 'mm:
memcg: subtree stats flushing and thresholds'.
- In the series 'Multi-size THP for anonymous memory' Ryan Roberts
has added a runtime opt-in feature to transparent hugepages which
improves performance by allocating larger chunks of memory during
anonymous page faults.
- Matthew Wilcox has also contributed some cleanup and maintenance
work against eh buffer_head code int he series 'More buffer_head
cleanups'.
- Suren Baghdasaryan has done work on Andrea Arcangeli's series
'userfaultfd move option'. UFFDIO_MOVE permits userspace heap
compaction algorithms to move userspace's pages around rather than
UFFDIO_COPY'a alloc/copy/free.
- Stefan Roesch has developed a 'KSM Advisor', in the series 'mm/ksm:
Add ksm advisor'. This is a governor which tunes KSM's scanning
aggressiveness in response to userspace's current needs.

stack traces for secondary-level allocators, in the series 'kasan:
save mempool stack traces'.
- Andrey also performed some KASAN maintenance work in the series
'kasan: assorted clean-ups'.
- David Hildenbrand has gone to town on the rmap code. Cleanups, more
pte batching, folio conversions and more. See the series 'mm/rmap:
interface overhaul'.

ksmbd: don't allow O_TRUNC open on read-only share
When file is changed using notepad on read-only share(read_only = yes in ksmbd.conf), There is a problem where existing data is truncated. notepad in windows try to O_TRUNC open(FILE_OVERWRITE_IF) and all data in file is truncated. This patch don't allow O_TRUNC open on read-only share and add KSMBD_TREE_CONN_FLAG_WRITABLE check in smb2_set_info().

ksmbd: Remove usage of the deprecated ida_simple_xx() API
ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). This is less verbose. Note that the upper limit of ida_simple_get() is exclusive, but the one of ida_alloc_range() is inclusive. So change a 0xFFFFFFFF into a 0xFFFFFFFE in order to keep the same behavior.
