 * NAME
 *	move_pages10.c
 *
 * DESCRIPTION
 *      Failure when flags passed to move_pages is invalid.
 *
 * ALGORITHM
 *
 *      1. Pass invalid flag to move_pages().
 *      2. Check if errno is set to EINVAL.
 *
 * USAGE:  <for command-line>
 *      move_pages10 [-c n] [-i n] [-I x] [-P x] [-t]
 *      where,  -c n : Run n copies concurrently.
 *              -i n : Execute test n times.
 *              -I x : Execute test for x seconds.
 *              -P x : Pause for x seconds between iterations.
 *              -t   : Turn on syscall timing.
 *
 * History
 *	05/2008 Vijay Kumar
 *		Initial Version.
