Linus Torvalds 3026c6e4f2 Merge tag 'slab-for-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/mm/slab 
Pull slab fixes from Vlastimil Babka:

 - 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)

* tag 'slab-for-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/mm/slab:
  mm/slab: take n->list_lock in __slab_try_return_freelist() to avoid race
  mm/slab: disallow kfree_rcu_sheaf() on PREEMPT_RT again
