- * It tests the duplicate mlock result:
- * - the ulimit of lock page is 64k
- * - allocate address area 64k starting from p
- * - mlock [p -- p + 30k]
- * - Then mlock address [ p -- p + 40k ]
- *
- * It should succeed since totally we locked
- * 40k < 64k limitation.
- *
- * It should not be run with CAP_IPC_LOCK.
