[GIT PULL] slab fixes for 7.0-rc2

[Vlastimil Babka (SUSE)]

Hi Linus,

please pull the latest slab fixes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git tags/slab-for-7.0-rc2

Thanks,
Vlastimil

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

- Fix for slab->stride truncation on 64k page systems due to short type.
  It was not due to races and lack of barriers in the end. (Harry Yoo)

- Fix for severe performance regression due to unnecessary sheaf refill
  restrictions exposed by mempool allocation strategy. (Vlastimil Babka)

- Stable fix for potential silent percpu sheaf flushing failures on
  PREEMPT_RT. (Vlastimil Babka)
