I must have used this sentence incorrectly: I meant what you described,
the kernel accepting the transfer and the module submitting it to
hardware whenever able.
Also, strictly speaking (and to avoid confusion if I failed further at
English expression in my previous emails) aio_submit itself does
succeed, so in a sense the kernel already accepts the transfer. The
issue is that the transfer completion happens immediately after, with
this EAGAIN status.
