Subject: slab common: add functions for kmem_cache_node access
The patchset provides two new functions in mm/slab.h and modifies SLAB and
SLUB to use these. The kmem_cache_node structure is shared between both
allocators and the use of common accessors will allow us to move more code
into slab_common.c in the future.
This patch (of 3):
These functions allow to eliminate repeatedly used code in both SLAB and
SLUB and also allow for the insertion of debugging code that may be needed
in the development process.
