SubjectRe: [PATCH -v2 -mm] add extra free kbytes tunable

I suggested a patch from BFS that would raise kswapd to the same priority
of the task that triggered it (not completely up to rt, but the highest
possible in that case) and I'm waiting to hear if that helps for Satoru's
test case before looking at alternatives. We could also extend the patch
to raise the priority of an already running kswapd if a higher priority
task calls into the page allocator's slowpath.
