Shouldn't depend on the disktype. As long as it's blktap, not blkback on
a raw vdi, all disk drivers depend on this.

The io_setup change you're referring might rather be the old way of
doing things. It made io_setup return an fd to poll, if the io_setup
caller calls with a 'magic' (1, actually) aio_ctx value.
