Greg Kurz 570fe439e5 virtio-blk: Fix rollback path in virtio_blk_data_plane_start() ... When dataplane multiqueue support was added in QEMU 2.7, the path that would rollback guest notifiers assignment in case of error simply got dropped. Later on, when Error was added to blk_set_aio_context() in QEMU 4.1, another error path was introduced, but it ommits to rollback both host and guest notifiers. It seems cleaner to fix the rollback path in one go. The patch is simple enough that it can be adjusted if backported to a pre-4.1 QEMU.
