No that's fine, I'll fix it up here - minimally for the stable backports and do
the rewrite later.
BTW I tried to reproduce the Old OOM hangs from LTP (STARS 9001304674, 9001281305)
to prove that this fix solves those too, but I can't seem to reproduce the same
deadlock without this fix on 4.17 kernel.
