This is the async version of bdrv_aio_cancel, which doesn't block the caller. It guarantees that the cb is called either before returning or some time later. bdrv_aio_cancel can base on bdrv_aio_cancel_async, later we can convert all .io_cancel implementations to .io_cancel_async, and the aio_poll is the common logic. In the end, .io_cancel can be dropped. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
