Eric Paris 808ffa3d30 tty_open can return to userspace holding tty_mutex ... __tty_open could return (to userspace) holding the tty_mutex thanks to a regression introduced by 4a2b5fddd5 ("Move tty lookup/reopen to caller"). This was found by bisecting an fsfuzzer problem. Admittedly I have no idea how it managed to tickle this 100% reliably, but it is clearly a regression and when hit leaves the box in a completely unusable state. This patch lets the fsfuzzer test complete every time.
