I looked at this a bit, and it turns that while this indeed changes the
behavior for discard, the other ioctls had the return 0 when nothing
was submitted before the thread got killed behavior, and this makes
discard match them.
Given that we won't return from the system call for a fatal kill it
should not matter. Adding Keith who wrote all this to confirm.
