And another patch we already discussed.
wait_event_timeout(wq, true, 0) still returns 0, this doesn't look
right, and this doesn't match __wait_event_timeout(timeout => 0).
Sure, most probably nobody uses the constant timeout == 0, but this
can break the code which does something like
if (nonblock)
timeout = 0;
else
timeout = TIMEOUT;
success = wait_event_timeout(wq, CONDITION, timeout);
