/*

 * The generic ipc64_perm structure:

 * Note extra padding because this structure is passed back and forth

 * between kernel and user space.

 *

 * ipc64_perm was originally meant to be architecture specific, but

 * everyone just ended up making identical copies without specific

 * optimizations, so we may just as well all use the same one.

 *

 * Pad space is left for:

 * - 32-bit mode_t on architectures that only had 16 bit

 * - 32-bit seq

 * - 2 miscellaneous 32-bit values
