25 * NAME
26 *	move_pages01.c
27 *
28 * DESCRIPTION
29 *      Test retrieval of NUMA node
30 *
31 * ALGORITHM
32 *      1. Allocate pages in NUMA nodes A and B.
33 *      2. Use move_pages() to retrieve the NUMA node of the pages.
34 *      3. Check if the NUMA nodes reported are correct.
35 *
36 * USAGE:  <for command-line>
37 *      move_pages01 [-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.
