Subject: virtio-scsi: Call virtio_add_queue_aio
X-Git-Tag: v2.7.0-rc0~3^2~17
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1c627137c10ee2dcf59e0383ade8a9abfa2d4355;p=thirdparty%2Fqemu.git

virtio-scsi: Call virtio_add_queue_aio

AIO based handler is more appropriate here because it will then
cooperate with bdrv_drained_begin/end. It is needed by the coming
revert patch.
