However, have you tried the existing non passthrough code? This patch seems to break it. I've not looked at the details though. I don't think you need to touch to sbc.c. we should not need to know the type of underlying devices with passthough. Can you add a new device type such as struct device_type_template sg_template? __cmd_done_passthrough() doesn't need to call post_cmd_done(), I think because post_cmd_done() checks the pending commands. With passthrough, there is no pending commands.
