[Qemu-devel] [PATCH v4 15/20] quorum: Convert quorum_aiocb_info.cancel to .cancel_async

[Fam Zheng <famz@redhat.com>]

Before, we cancel all the child requests with bdrv_aio_cancel, then free
the acb..

Now we just kick off asynchronous cancellation of child requests and
return, we know quorum_aio_cb will be called later, so in the end
quorum_aio_finalize will take care of calling the caller's cb.
