+ * 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
