It doesn't have default: before 0: or involve a print, so reordering is not as necessary. However, that function doesn't clear ordered_tags in the MSG_SIMPLE_TAG case, which seems problematic if the device is ever changed from ordered to simple. You might want to address that in this patch too. --- Rob Elliott HP Server Storage -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
