29 * 2. IORING_OP_POLL_REMOVE - removes a file descriptor being monitored. When
31 * re-added with the new poll mask, so this operation is also used as part
33 * 3. IORING_OP_TIMEOUT - added every time a blocking syscall is made to wait
34 * for events. This operation self-cancels if another event completes
38 * the "cq ring". Ring entries are called "sqe" and "cqe", respectively.
42 * ctx->submit_list so that fdmon_io_uring_wait() can submit IORING_OP_POLL_ADD
