At least in the block layer, AIO callbacks may never be called before
the submission function has returned. I think this makes the DMA helpers
provide the same behaviour.
But I'm not sure if the definition of the AIOCB struct isn't private to
the block layer.
Yes, it is; I would add a getter that is specific to the DMAAIOCB.
