* NAME
|
|
* move_pages06.c
|
|
*
|
|
* DESCRIPTION
|
|
* Failure when NUMA node is invalid.
|
|
*
|
|
* ALGORITHM
|
|
*
|
|
* 1. Pass a non-existent NUMA node number to move_pages().
|
|
* 2. Check if errno is set to ENODEV.
|
|
*
|
|
* USAGE: <for command-line>
|
|
* move_pages06 [-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.
