Hi Linus,

please pull the latest slab fixes from:

git://git.kernel.org/pub/scm/linux/kernel/git/mm/slab.git tags/slab-for-7.3-rc2

Note the slab tree has been moved since the last PR from vbabka/slab.git
to the new mm/ namespace.

Thanks,
Vlastimil

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

- Stable fix for an ABA issue causing slab list corruption introduced in 7.2.
(Harry Yoo, with big thanks to Hyunwoo Kim for the thorough report and
initial version of the fix)

- Fix for 7.3 regression of kvfree_rcu() on PREEMPT_RT which can cause a
deadlock from the set_cpus_allowed_force() caller. (Vlastimil Babka)
