90 * that they pack the same way on 32-bit and 64-bit architectures (to
91 * avoid incompatibility between 32-bit userspace and 64-bit kernels).

94 * - Make sure that any structure larger than 4 bytes is padded to a
95 * multiple of 8 bytes. Otherwise the structure size will be
96 * different between 32-bit and 64-bit architectures.
