Merge branch 'slab/for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/linux
Pull SLAB changes from Pekka Enberg: "New and noteworthy: * More SLAB allocator unification patches from Christoph Lameter and others. This paves the way for slab memcg patches that hopefully will land in v3.8. * SLAB tracing improvements from Ezequiel Garcia. * Kernel tainting upon SLAB corruption from Dave Jones. * Miscellanous SLAB allocator bug fixes and improvements from various people." * 'slab/for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/linux: (43 commits) slab: Fix build failure in __kmem_cache_create() slub: init_kmem_cache_cpus() and put_cpu_partial() can be static mm/slab: Fix kmem_cache_alloc_node_trace() declaration Revert "mm/slab: Fix kmem_cache_alloc_node_trace() declaration" mm, slob: fix build breakage in __kmalloc_node_track_caller mm/slab: Fix kmem_cache_alloc_node_trace() declaration mm/slab: Fix typo _RET_IP -> _RET_IP_ mm, slub: Rename slab_alloc() -> slab_alloc_node() to match SLAB mm, slab: Rename __cache_alloc() -> slab_alloc() mm, slab: Match SLAB and SLUB kmem_cache_alloc_xxx_trace() prototype mm, slab: Replace 'caller' type, void* -> unsigned long mm, slob: Add support for kmalloc_track_caller() mm, slab: Remove silly function slab_buffer_size() mm, slob: Use NUMA_NO_NODE instead of -1 mm, sl[au]b: Taint kernel when we detect a corrupted slab slab: Only define slab_error for DEBUG slab: fix the DEADLOCK issue on l3 alien lock slub: Zero initial memory segment for kmem_cache and kmem_cache_node Revert "mm/sl[aou]b: Move sysfs_slab_add to common" mm/sl[aou]b: Move kmem_cache refcounting to common code ...
