io_uring: don't restrict issue_flags for io_openat

isilence · axboe · commit e45cff588588 · 2021-03-05T09:52:29.000-07:00
45d189c ("io_uring: replace force_nonblock with flags") did something strange for io_openat() slicing all issue_flags but IO_URING_F_NONBLOCK. Not a bug for now, but better to just forward the flags. Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
