2 * include/asm-xtensa/msgbuf.h
3 *
4 * The msqid64_ds structure for the Xtensa architecture.
5 * Note extra padding because this structure is passed back and forth
6 * between kernel and user space.
7 *
8 * Pad space is left for:
9 * - 64-bit time_t to solve y2038 problem
10 * - 2 miscellaneous 32-bit values
