Subject: [GIT PULL] slab updates for 6.3-rc1

Linus,

please pull the latest slab updates from:

  git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git tags/slab-for-6.3

This time it's just a bunch of smaller cleanups and fixes for SLAB and SLUB:

- Make it possible to use kmem_cache_alloc_bulk() early in boot when
  interrupts are not yet enabled, as code doing that started to appear via
  new maple tree users (by Thomas Gleixner).

- Fix debugfs-related memory leak in SLUB (by Greg Kroah-Hartman).

- Use the standard idiom to get head page of folio (by SeongJae Park)

- Simplify and inline is_debug_pagealloc_cache() in SLAB (by lvqian)

- Remove unused variable in SLAB (by Gou Hao)
