43 * Make sure that all structs defined in this file remain laid out so
44 * that they pack the same way on 32-bit and 64-bit architectures (to
45 * avoid incompatibility between 32-bit userspace and 64-bit kernels).
47 * - Do not use pointer types -- pass pointers in uint64_t instead.
48 * - Make sure that any structure larger than 4 bytes is padded to a
49 * multiple of 8 bytes. Otherwise the structure size will be
50 * different between 32-bit and 64-bit architectures.
