Instead of requiring a flag we could simply check for the sglist_count to be non-zero instead of requiring multiple pieces of information to be in sync. I'd also be tempted to remove the wrappers and just expose what is __target_submit_cmd now to the drivers, but that can be done independently as a cleanup. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
