Subject: [GIT PULL] slab updates for 6.13 v2

Hi Linus,

please pull the latest slab updates from:

  git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git tags/slab-for-6.13-v2

One new feature and non-critical fixes (mostly related to debugging).
No conflicts to be expected, AFAIK.

After fixing up the bug that was in the v1 pull 9 days ago, I've only added
Geert's fix on top 5 days ago, and it was all in -next.

Thanks,
Vlastimil

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

- Add new slab_strict_numa boot parameter to enforce per-object memory policies
  on top of slab folio policies, for systems where saving cost of remote
  accesses is more important than minimizing slab allocation overhead
  (Christoph Lameter)

- Fix for freeptr_offset alignment check being too strict for m68k (Geert
  Uytterhoeven)

- krealloc() fixes for not violating __GFP_ZERO guarantees on krealloc() when
  slub_debug (redzone and object tracking) is enabled (Feng Tang)

- Fix a memory leak in case sysfs registration fails for a slab cache, and also
  no longer fail to create the cache in that case (Hyeonggon Yoo)

- Fix handling of detected consistency problems (due to buggy slab user) with
  slub_debug enabled, so that it does not cause further list corruption bugs
  (yuan.gao)

- Code cleanup and kerneldocs polishing (Zhen Lei, Vlastimil Babka)
