 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.
