Merge tag 'slab-for-6.9-rc7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab

Pull slab fixes from Vlastimil Babka:

 - 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.
