[GIT PULL] slab updates for 7.2

[Vlastimil Babka (SUSE)]

Hi Linus,

please pull the latest slab updates from:

  git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git tags/slab-for-7.2

One conflict was reported with the drm tree. The kmem_cache_alloc_bulk() call
we adjust has moved to a different function there:

https://lore.kernel.org/all/ahoZ7OCzxTAbGMtO@xxxxxxxxxxxxx/

Thanks,
Vlastimil

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

- Support for "allocation tokens" (currently available in Clang 22+) for
  smarter partitioning of kmalloc caches based on the allocated object type,
  which can be enabled instead of the "random" per-caller-address-hash
  partitioning. It should be able to deterministically separate types containing
  a pointer from those that do not. (Marco Elver)

- Improvements and simplification of the kmem_cache_alloc_bulk() and
  mempool_alloc_bulk() API. This includes adaptation of callers.
  (Christoph Hellwig)

- Performance improvements and cleanups related mostly to sheaves refill.
  (Hao Li, Shengming Hu, Vlastimil Babka)

- Several fixups for the slabinfo tool. (Xuewen Wang)
