Pull slab fix from Mike Snitzer:
 "This fixes the broken duplicate slab name check in
  kmem_cache_sanity_check() that has been repeatedly reported (as
  recently as today against Fedora rawhide).

  Pekka seemed to have it staged for a late 3.15-rc in his 'slab/urgent'
  branch but never sent a pull request, see:
      https://lkml.org/lkml/2014/5/23/648"
