May I ask you to remove "epoll: ensure ep_poll() doesn't miss wakeup events" from your -mm queue? Jason lately found out that the patch does not fully solve the problem and this one patch is a second attempt to do things correctly in a different way (namely to do the final check under the lock). Previous changes are not needed.

Where do we stand with Khazhismel's "eventpoll: fix missing wakeup for ovflist in ep_poll_callback"?
