Cover letter [Slub cleanup 0/9] Slub: cleanups V2
V1->V2:
- Rebase against 3.4-rc6
A series of cleanup patches that resulted from the rework of the allocation paths to not disable interrupts.
The patches remove the node field from kmem_cache_cpu and generally cleans up code in the critical paths. The removal of the node field increases the cache friendliness of the hotpaths and results in a slight performance increase.
