v1 -> v2: - Use copy_to_iter() to send control queue response This patch series causes vhost-scsi control queue TMF requests to be explicitly rejected rather than implicitly ignored in order to prevent a guest virito-scsi driver to wait indefinitely for a response to a SCSI TMF request. In addition, control queue address notification operations (VIRTIO_SCSI_T_AN_*) get an effective no-op response. Patch 1/4 implements a control queue handler modeled after the existing request queue handler. There is no commonality between the two handlers. Patch 2/4 factors out the common processing code from the control queue handler into separate routines. Patch 3/4 modifies the request handler to use the common processing routines. Patch 4/4 uses copy_to_iter() to send back control queue responses.
