OK, that's the part I don't understand. It seems like transport_allocate_data_tasks() will always make the individual task_sg by taking apart the cmd_sg that's passed in, and that's the only place that I can see where we create multiple tasks for a single cmd. So why do we need to splice the task_sgs back together, when we have the original cmd_sg in one piece from the beginning? - R. -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
