io_uring: restrict IORING_SETUP_SQPOLL to root
This options spawns a kernel side thread that will poll for submissions (and completions, if IORING_SETUP_IOPOLL is set). As this allows a user to potentially use more cycles outside of the normal hierarchy, restrict the use of this feature to root. Signed-off-by: Jens Axboe <axboe@kernel.dk>
