Sure.

But. Tejun, Rafael, I have to rely on your review. I have no idea how
can I test this change. Hopfully it is simple enough, though.

And. wait_event_freezable_timeout() obviously has another problem,
although I hope this is fine. The caller can spend a lot of time in
refrigerator, shouldn't we update "timeout" in this case? I hope we
shouldn't.

Oleg.
