|
* [Description]
|
|
*
|
|
* Conversion of the first kself test in cgroup/test_memcontrol.c.
|
|
* This test creates two nested cgroups with and without enabling the
|
|
* memory controller.
|
|
*
|
|
* The LTP API automatically adds controllers to subtree_control when
|
|
* a child cgroup is added. So unlike the kselftest we remove the
|
|
* controller after it being added automatically.
