Do you mean make it so that all kmallocs come from the root cgroup's slabs?
We would really like to account kmallocs in general (and all the other
slab types) to the right cgroup...
That said, I'm probably going to concentrate on accounting specially
marked caches only, for now, since there seems to be a strong
opposition on accounting everything, even though I don't understand
this point of view.
