Hello, Namhyung!

I personally like the idea very much. With a growing number of kmem_caches
/proc/slabinfo getting close to it's limit, so having a more flexible
interface makes a lot of sense.

I'd personally prefer kmem_cache or slab_cache, just in case somebody later
would propose an iterator over individual slab objects within a kmem_cache.

Thanks!
