Merge branch 'net-kmem-cache-create'

Kunwu Chan says:

====================
net: Use KMEM_CACHE instead of kmem_cache_create

As Jiri Pirko suggests,
I'm using a patchset to cleanup the same issues in the 'net' module.
Use the new KMEM_CACHE() macro instead of direct kmem_cache_create
to simplify the creation of SLAB caches.

Some cache names are changed to be the same as struct names.
This change is recorded in the changelog for easy reference.
It's harmless cause it's used in /proc/slabinfo to identify this cache.
