Merge tag 'slab-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab

Pull slab updates from Vlastimil Babka:

 - mempool_alloc_bulk() support for upcoming users in the block layer
   that need to allocate multiple objects at once with the mempool's
   guaranteed progress semantics, which is not achievable with an
   allocation single objects in a loop. Along with refactoring and
   various improvements (Christoph Hellwig)

 - Preparations for the upcoming separation of struct slab from struct
   page, mostly by removing the struct folio layer, as the purpose of
   struct folio has shifted since it became used in slab code (Matthew
   Wilcox)

 - Modernisation of slab's boot param API usage, which removes some
   unexpected parsing corner cases (Petr Tesarik)

 - Refactoring of freelist_aba_t (now struct freelist_counters) and
   associated functions for double cmpxchg, enabled by -fms-extensions
   (Vlastimil Babka)

 - Cleanups and improvements related to sheaves caching layer, that were
   part of the full conversion to sheaves, which is planned for the next
   release (Vlastimil Babka)
