If IORING_SETUP_COOP_TASKRUN is set to use cooperative scheduling for running task_work, then IORING_SETUP_TASKRUN_FLAG can be set so the application can tell if task_work is pending in the kernel for this ring. This allows use cases like io_uring_peek_cqe() to still function appropriately, or for the task to know when it would be useful to call io_uring_wait_cqe() to run pending events.
