/*

 * generic msqid64_ds structure.

 *

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

 * between kernel and user space.

 *

 * msqid64_ds 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.

 *

 * 64 bit architectures typically define a 64 bit __kernel_time_t,

 * so they do not need the first three padding words.

 * On big-endian systems, the padding is in the wrong place.

 *

 * Pad space is left for:

 * - 64-bit time_t to solve y2038 problem

 * - 2 miscellaneous 32-bit values
