tiny mq_open optimization
A very small cleanup for mq_open. We do not have to call set_close_on_exit if we create the file descriptor right away with the flag set. We have a function for this now. The resulting code is smaller and a tiny bit faster. Signed-off-by: Ulrich Drepper <drepper@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
