Why's that? I don't see why cpuset memory nodemasks can't coexist
with, say, the RG memory controller. They're attempting to solve
different problems, and I can see situations where you might want to
use both at once.

Agreed, if we can come up with a definition of e.g. memory controller
that everyone agrees is suitable for their needs. You're assuming
that's so a priori, I'm not yet convinced.

And I'm not trying to get another memory controller into the kernel,
I'm just trying to get a standard process aggregation into the kernel
(or rather, take the one that's already in the kernel and make it
possible to hook other controller frameworks into it), so that the
various memory controllers can become less intrusive patches in their
own right.
