Next, it makes no sense to restrict your change to NET_IP_ALIGN==0 Simply handle any case, by undoing the reservation if it's getting in the way. If there isn't an appropriate helper for this, add one. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
