we always use a 64bit off_t when communicating with userland. its up to libraries to do the proper padding and aio_error abstraction

Fields

aio_data: u64

these are internal to the kernel/libc. data to be returned in event's data */

aio_key: u32

the kernel sets aio_key to the req #

aio_rw_flags: rwf_t

extra parameters

aio_flags: u32

flags for the "struct iocb"

aio_resfd: u32

If the IOCB_FLAG_RESFD flag of "aio_flags" is set, this is an eventfd to signal AIO readiness to
