Before, scsi_req_cancel will take ownership of the canceled request and unref it. We did this because we didn't know whether AIO CB will be called or not during the cancelling, so we set the io_canceled flag before calling it, and skip unref in the potentially called callbacks, which is not very nice. Now, bdrv_aio_cancel has a stricter contract that the completion callbacks are always called, so we can remove the checks of req->io_canceled and just unref it in callbacks. It will also make implementing asynchronous cancellation easier. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |
