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mm/slab.c: cleanup outdated comments and unify variables naming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
