92 * avoid incompatibility between 32-bit userspace and 64-bit kernels).
94 * - Do not use pointer types -- pass pointers in __u64 instead.
95 * - Make sure that any structure larger than 4 bytes is padded to a
96 * multiple of 8 bytes. Otherwise the structure size will be
97 * different between 32-bit and 64-bit architectures.
