Merge tag 'slab-for-7.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mm/slab

Pull slab updates from Harry Yoo:

 - Performance improvement of the sheaf prefill API, by allowing the
   barn to hold a partial sheaf and refilling sheaves from the barn.
   This improves will-it-scale mmap1 throughput by 24% on the maple_node
   cache (Hao Li)

 - Restore memcg accounting of ipc msg_msg allocations, lost with e.g.
   CONFIG_SLAB_BUCKETS=n where the allocations fall back to the general
   kmalloc caches (Kees Cook)

 - Fix an old race between kmem_cache_destroy() and slab_late_init(),
   where a cache destroyed late in the boot process tries to release a
   kobject that was never initialized (Imre Kaloz)

 - Remove slab_folio(), the last use of struct folio in slab code
   (Matthew Wilcox)

 - Reject kmalloc() requests above KMALLOC_MAX_SIZE explicitly with a
   warning and NULL return instead of relying on the page allocator's
   order check (Zi Yan)

 - Various minor fixes and cleanups (Hao Li, Karl Mehltretter, Kees
   Cook, Longlong Xia)
