Pull non-MM updates from Andrew Morton:

- "ocfs2/dlm: bound peer-controlled lengths in the o2dlm" (Bryam
Vargas)

Validate and bound all input lengths and count fields in the o2dlm
migration and recovery receive handlers to prevent memory corruption
and kernel panics from malformed cluster messages

- "ocfs2: validate xattr entry bounds" (Cen Zhang)

Validate OCFS2 extended attribute entry name and value bounds during
metadata reads to prevent out-of-range memory accesses during
retrieval or listing operations.

- "taskstats: fix cgroupstats invalid fd handling and add selftests"
(Yiyang Chen)

Return -EBADF when cgroupstats receives an invalid file descriptor to
prevent caller hangs and misleading success ACKs. Add a kselftest to
validate valid cgroup v1 queries and verify proper error handling
across different Netlink flag combinations.

- "misc lib/raid/ improvements v2" (Christoph Hellwig)

Improve benchmark-based algorithm selection for the XOR and RAID6
libraries, add KUnit benchmark tests, and cleanup minor
implementation details.

- "ocfs2: cluster: o2hb_region_pin() fixes" (Joseph Qi)

Fix sleeping-in-atomic, lock order inversion and error-path cleanup
bugs in o2hb_region_pin() by releasing o2hb_live_lock across sleeping
configfs_depend_item() calls and using unlocked variants from
callback context. Ensure failed pin attempts properly decrement user
counts and unpin partially initialized heartbeat regions to prevent
memory leaks and unprotected states.

- "lib/ucs2_string.c: fix out-of-bounds read in ucs2_strnlen()"
(Vincent Mailhol)

Fix an off-by-one which could cause an out-of-bounds read.

- "ocfs2: harden heartbeat teardown races" (Cen Zhang)

Fix two OCFS2 heartbeat/o2net teardown races found by KASAN.

- "taskstats: tidy up the cpumask command path" *Bradley Morgan)

make two small cleanups in kernel/taskstats.c.

- "ocfs2: validate active orphan slots during inode read" (ZhengYuan
Huang)

Validate active ordinary and append-DIO orphan slots read from OCFS2
dinodes at the metadata boundary to prevent corrupted slot indices
from causing out-of-bounds array accesses.

- "ocfs2: bound-check both readdir re-validation scans" (Zhan Xusheng)

Enforce strict boundary checks on directory entry record lengths and
offset calculations during OCFS2 directory re-scans to prevent
out-of-bounds memory reads and directory position corruption.

xor: enable lock context analysis

Patch series "misc lib/raid/ improvements v2".

This series improves the benchmark-based algorithm selection and adds
kunit benchmarks for both the XOR and raid6 libraries, and tidies up a few
very minor other bits.


This patch (of 8):

The code doesn't have any locking, so this is trivial.

Merge tag 'mm-nonmm-stable-2026-04-15-04-20' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull non-MM updates from Andrew Morton:

some historical cruft which is no longer needed. Also some
documentation fixups

/proc/sys/kernel/hung_task_detect_count

- "tools/getdelays: use the static UAPI headers from
tools/include/uapi" (Thomas Weißschuh)

system-provided ones

- "watchdog/hardlockup: Improvements to hardlockup" (Mayank Rungta)

documentation

- "lib/bch: fix undefined behavior from signed left-shifts" (Josh Law)

A couple of small/theoretical fixes in the bch code

- "ocfs2/dlm: fix two bugs in dlm_match_regions()" (Junrui Luo)

- "cleanup the RAID5 XOR library" (Christoph Hellwig)

A quite far-reaching cleanup to this code. I can't do better than to
quote Christoph:

"The XOR library used for the RAID5 parity is a bit of a mess right
now. The main file sits in crypto/ despite not being cryptography
and not using the crypto API, with the generic implementations
sitting in include/asm-generic and the arch implementations
sitting in an asm/ header in theory. The latter doesn't work for
many cases, so architectures often build the code directly into
the core kernel, or create another module for the architecture
code.

Change this to a single module in lib/ that also contains the
architecture optimizations, similar to the library work Eric
Biggers has done for the CRC and crypto libraries later. After
that it changes to better calling conventions that allow for
smarter architecture implementations (although none is contained
here yet), and uses static_call to avoid indirection function call
overhead"

- "lib/list_sort: Clean up list_sort() scheduling workarounds"
(Kuan-Wei Chiu)

Clean up this library code by removing a hacky thing which was added
for UBIFS, which UBIFS doesn't actually need

Enable support of the LUKS-encrypted device dump target on arm64 and
powerpc

- "ocfs2: consolidate extent list validation into block read callbacks"
