Constant syscall::flag::EVENT_URING

pub const EVENT_URING: EventFlags;

The event represents an io_uring getting a new submission or completion pushed onto it, which means that a process receiving this event can poll that queue and process its events.

This event may be sent as all other Redox events by writing to the fd, but to reduce context switches as much as possible, the kernel may also compare the epoch counters of a process's io_urings and generate the event automatically.
