Subject: [GIT PULL] slab fix for 6.0-rc7

Linus,

please pull the latest slab changes from

  git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git tags/slab-for-6.0-rc7

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

- Fix a possible use-after-free in SLUB's kmem_cache removal, introduced in
  this cycle, by Feng Tang.

- WQ_MEM_RECLAIM dependency fix for the workqueue-based cpu slab flushing
  introduced in 5.15, by Maurizio Lombardi.

- Add missing KASAN hooks in two kmalloc entry paths, by Peter Collingbourne.

- A BUG_ON() removal in SLUB's kmem_cache creation when allocation fails (too
  small to possibly happen in practice, syzbot used fault injection), by Chao
  Yu.

Thanks,
Vlastimil
