A bit of addition.

Let's *please* think through how memcg should be configured and
different knobs / limits interact with each other and come up with a
consistent scheme before adding more shits on top.  This "oh I know
this use case and maybe that behavior is necessary too, let's add N
different and incompatible ways to mix and match them" doesn't fly.
Aren't we suppposed to at least have learned that already?
