[PATCH v2 0/2] common entry point for kmem_cache_free

[Glauber Costa <glommer@parallels.com>]

The goal of this patchset is to provide a single entry point for
kmem_cache_free. Other functions, such as the allocation itself, and kmalloc
could easily follow.

The main problem here, is that if we keep the allocator-specific functions
in their .c file, we lose the ability to inline their fast paths. Being this
such a critical path, we would like to keep doing so.

During the last discussion around this (https://lkml.org/lkml/2012/10/22/639),
JoonSoo Kim suggested that we could achieve this by just including the
allocator-specific .c files in slab_common.c, a suggestion I considered but
quickly disregarding fearing a quite ugly end result.

Turns out it doesn't look so bad. So please let me know what you think.

Thanks
