That avoids the races with the event you're waiting for. # # The same goes for poll/select logic: the "poll_wait()" goes first, and # then you check the things you're polling for. # # Of course, if you use locking, the ordering doesn't matter since the # lock will serialize with anything that changes the state you're looking # at. That's not the case here, though. # # So move the poll_wait() first in pipe_poll(), before you start looking # at the pipe state. # # Fixes: 8cefc107ca54 ("pipe: Use head and tail pointers for the ring, not cursor and length") # Cc: David Howells <dhowells@redhat.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # <
