         * Pad strcture to 128 bytes. Remember to update the
         * pad size when you add new members. We use a fixed
         * size structure to avoid compatibility problems with
         * future versions, and we leave extra space for additional
         * members. We use fixed size members because this strcture
         * comes out of a read(2) and we really don't want to have
         * a compat on read(2).
