Pull slab updates from Vlastimil Babka:

 - Move the kfree_rcu() implementation from RCU to SLAB subsystem
   (Uladzislau Rezki)

   The kfree_rcu() implementation has been historically maintained in
   the RCU subsystem. At LSF/MM we agreed to move it to SLAB, where it
   more logically belongs. The batching is planned be more integrated
   with SLUB internals in the future, while using the RCU APIs like any
   other subsystem.

 - Fix for kernel-doc warning (Randy Dunlap)
