Yes and no. I was kidding about "scheduler improvements" part.
(they're mostly NUMA-only)

But of course memload, read and write latencies aren't necessarily caused b=
y=20
scheduler itself.=20
(burn also reads a file)

The easiest thing to do would be to add staircase to -mm and see what happe=
ns.
It shouldn't be hard to port. (in fact, it may apply cleanly)
