[GIT PULL] slab fixes for 6.9-rc7

[Vlastimil Babka]

Hi Linus,

please pull the latest slab hot-fixes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git tags/slab-for-6.9-rc7-fixes

Thanks,
Vlastimil

======================================

- Fix for cleanup infrastructure (Dan Carpenter)

  This makes the __free(kfree) cleanup hooks not crash on error pointers.

- SLUB fix for freepointer checking (Nicolas Bouchinet)

  This fixes a recently introduced bug that manifests when init_on_free,
  CONFIG_SLAB_FREELIST_HARDENED and consistency checks (slub_debug=F) are
  all enabled, and results in false-positive freepointer corrupt reports
  for caches that store freepointer outside of the object area.

      mm/slab: make __free(kfree) accept error pointers

Nicolas Bouchinet (1):
      mm/slub: avoid zeroing outside-object freepointer for single free
