-Subject: [PATCH] virtio-scsi: fix ctrl and event handler functions in
- dataplane mode
-
-Commit f34e8d8b8d48d73f36a67b6d5e492ef9784b5012 ("virtio-scsi: prepare
-virtio_scsi_handle_cmd for dataplane") prepared the virtio-scsi cmd
-virtqueue handler function to be used in both the dataplane and
-non-datpalane code paths.
-
-It failed to convert the ctrl and event virtqueue handler functions,
-which are not designed to be called from the dataplane code path but
-will be since the ioeventfd is set up for those virtqueues when
-dataplane starts.
-
-Convert the ctrl and event virtqueue handler functions now so they
-operate correctly when called from the dataplane code path. Avoid code
-duplication by extracting this code into a helper function.
-
-Fixes: f34e8d8b8d48d73f36a67b6d5e492ef9784b5012 ("virtio-scsi: prepare virtio_scsi_handle_cmd for dataplane")
