Isn’t that still experimental?
From the current aio man page:
“Work has been in progress for some time on a
kernel state-machine-based implementation of asynchronous I/O (see
io_submit(2), io_setup(2), io_cancel(2), io_destroy(2),
io_getevents(2)), but this implementation hasn't yet matured to the
point where the POSIX AIO implementation can be completely
reimplemented using the kernel system calls.”
