Merge branch 'slab/next' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/linux
Pull slab changes from Pekka Enberg: "The biggest change is byte-sized freelist indices which reduces slab freelist memory usage: https://lkml.org/lkml/2013/12/2/64" * 'slab/next' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/linux: mm: slab/slub: use page->list consistently instead of page->lru mm/slab.c: cleanup outdated comments and unify variables naming slab: fix wrongly used macro slub: fix high order page allocation problem with __GFP_NOFAIL slab: Make allocations with GFP_ZERO slightly more efficient slab: make more slab management structure off the slab slab: introduce byte sized index for the freelist of a slab slab: restrict the number of objects in a slab slab: introduce helper functions to get/set free object slab: factor out calculate nr objects in cache_estimate
