When a parent cache does tune_cpucache, we need to propagate that to the
children as well. For that, we unfortunately need to tap into the slab core.

One of the todo list items for the common stuff is to have actually a
common kmem_cache structure. If we add a common callback then we could put
that also into the core.

At this point, I'd like to keep it this way if possible. I agree that it
would be a lot better living in a common location, and I commit to
helping you to move in that direction.

But I see no reason to have this commonization to happen first, as a
pre-requisite for this.
