6 * generic msqid64_ds structure.
7 *
8 * Note extra padding because this structure is passed back and forth
9 * between kernel and user space.
10 *
11 * msqid64_ds was originally meant to be architecture specific, but
12 * everyone just ended up making identical copies without specific
13 * optimizations, so we may just as well all use the same one.
14 *
15 * 64 bit architectures typically define a 64 bit __kernel_time_t,
16 * so they do not need the first three padding words.
17 * On big-endian systems, the padding is in the wrong place.
18 *
19 * Pad space is left for:
20 * - 64-bit time_t to solve y2038 problem
21 * - 2 miscellaneous 32-bit values
