Oh yeah, I think if you can still have IO running from inside the driver you want to move the target_remove_session call to _efct_tgt_node_free. We will then handle the case where a cmd has passed efct_node_find and got a ref to the efct_node but not yet reached target_init_cmd. When the cmd hits target_init_cmd lio will return a failure, efct_dispatch_frame will drop its ref, and then we will free the efct_node and lio session.
