Fields

opcode: u8

Operation opcode (AsyncOp variant).

flags: u8

Flags: FIXED_FILE, IO_LINK, IO_DRAIN, IO_HARDLINK.

ioprio: u16

Priority hint (ioprio class << 13 | ioprio data).

fd: u32

File descriptor (VFS fd) or IPC port id.

off: u64

File offset (for read/write) or endpoint id (for IPC).

addr: u64

Buffer virtual address (userspace pointer : validated by kernel).

len: u32

Buffer length in bytes.

op_flags: u32

Operation-specific flags (e.g. RW_FSYNC for write).

user_data: u64

Opaque correlation token : echoed in the CQE on completion.

personality: u16

Personality / capability context (silo token).

_pad: [u8; 22]

Padding to 64 bytes (cache-line aligned).
