[GIT PULL] slab updates for 7.1

[Vlastimil Babka (SUSE)]

Hi Linus,

please pull the latest slab updates from:

  git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git tags/slab-for-7.1

Thanks,
Vlastimil

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

- Sheaves performance improvements for systems with memoryless NUMA nodes,
  developed in response to regression reports. These mainly ensure that percpu
  sheaves exist and are used on cpus that belong to these memoryless nodes.
  (Vlastimil Babka, Hao Li).

- Cleanup API usage and constify sysfs attributes. (Thomas Weißschuh)

- Disable kfree_rcu() batching on builds intended for fuzzing/debugging that
  enable CONFIG_RCU_STRICT_GRACE_PERIOD. (Jann Horn)

- Add a kunit test for kmalloc_nolock()/kfree_nolock(). (Harry Yoo)
