  ocfs2: cache the mount context for dentry lock callbacks (2026-11-02 19:18:59 -0800)

22 patches. 17 are cc:stable.

Most are OCFS2 fixes. These address extended-attribute corruption,
missing attributes and kernel BUGs, along with crashes during cluster
configuration, lock migration, recovery and unmount. Extent movement
is also fixed to validate its range against a stable file size.

Three FAT changes prevent a failed-write/FIBMAP race from spuriously
making the filesystem read-only, correct directory link counts after
rename, and speed up file expansion. The reported QEMU benchmarks show
particularly large improvements on synchronous mounts.

A taint-string fix prevents an out-of-bounds read which can expose slab
contents in the kernel log. There are also build fixes for OpenRISC
modules on CPUs without hardware multiply and for Clang 24.
