25  * NAME
26  *	move_pages07.c
27  *
28  * DESCRIPTION
29  *      Failure when PID is invalid.
30  *
31  * ALGORITHM
32  *
33  *      1. Pass a non-existent pid to move_pages().
34  *      2. Check if errno is set to ESRCH.
35  *
36  * USAGE:  <for command-line>
37  *      move_pages07 [-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.
