5 * The generic ipc64_perm structure:
6 * Note extra padding because this structure is passed back and forth
7 * between kernel and user space.
8 *
9 * ipc64_perm was originally meant to be architecture specific, but
10 * everyone just ended up making identical copies without specific
11 * optimizations, so we may just as well all use the same one.
12 *
13 * Pad space is left for:
14 * - 32-bit mode_t on architectures that only had 16 bit
15 * - 32-bit seq
16 * - 2 miscellaneous 32-bit values
