Yeah *smallish* higher order allocations are fine, and we use them all the
time for things like stacks or networking.
But Aubrey (who somehow got removed from the cc list) wants to do order 9
allocations from userspace in his nommu environment. I'm just trying to be
realistic when I say that this isn't going to be robust and a userspace
solution is needed.
Oh, and also: I don't disagree with that limiting pagecache to some %
might be useful for other reasons.
