25 * NAME
26 * move_pages06.c
27 *
28 * DESCRIPTION
29 * Failure when NUMA node is invalid.
30 *
31 * ALGORITHM
32 *
33 * 1. Pass a non-existent NUMA node number to move_pages().
34 * 2. Check if errno is set to ENODEV.
35 *
36 * USAGE: <for command-line>
37 * move_pages06 [-c n] [-i n] [-I x] [-P x] [-t]
38 * where, -c n : Run n copies concurrently.
39 * -i n : Execute test n times.
40 * -I x : Execute test for x seconds.
41 * -P x : Pause for x seconds between iterations.
42 * -t : Turn on syscall timing.
43 *
44 * History
45 * 05/2008 Vijay Kumar
46 * Initial Version.
