Summary of patch series in this merge:

- "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.
