Submits the SQEs acquired via get_sqe() to the kernel. You can call this once after you have called get_sqe() multiple times to setup multiple I/O requests. Returns the number of SQEs submitted, if not used alongside IORING_SETUP_SQPOLL. If the io_uring instance is uses IORING_SETUP_SQPOLL, the value returned on success is not guaranteed to match the amount of actually submitted sqes during this call. A value higher or lower, including 0, may be returned. Matches the implementation of io_uring_submit() in liburing.
