Module ops 

Asynchronous I/O ABI types : stable across kernel versions.

Defines the AsyncOp opcode enum, AsyncSqe (submission queue entry), and AsyncCqe (completion queue event) as #[repr(C)] structs.

Structs

AsyncCqe

A single I/O completion, written by the kernel into the CQ ring.

AsyncSqe

A single I/O submission, written by userspace into the SQ ring.

Enums

AsyncOp

Operation opcode submitted through the async ring.

Constants

DEFAULT_RING_ENTRIES

Default SQE ring size (must be a power of two).

MAX_IN_FLIGHT

Maximum number of in-flight operations per ring.
