libcgroup: APIArgsTest Class Reference

Physically create new control group in kernel, with all parameters and values copied from its parent group. The group is created in all hierarchies, where the parent group exists. I.e. following code creates subgroup in all hierarchies, because all of them have root (=parent) group.
struct cgroup *foo = cgroup_new_cgroup("foo");

cgroup_create_cgroup_from_parent(foo, 0);

Todo:
what is this good for? Why the list of controllers added by cgroup_add_controller() is not used, like in cgroup_create_cgroup()? I can't crate subgroup of root group in just one hierarchy with this function!

Parameters
@@ -889,7 +889,7 @@ int
cgroup_convert_cgroup<

Read all information regarding the group from kernel. Based on name of the group, list of controllers and all parameters and their values are read from all hierarchies, where a group with given name exists. All existing controllers are replaced. I.e. following code will fill root with controllers from all hierarchies, because the root group is available in all of them.
struct cgroup *root = cgroup_new_cgroup("/");

cgroup_get_cgroup(root);

Todo:
what is this function good for? Why is not considered only the list of controllers attached by cgroup_add_controller()? What owners will return cgroup_get_uid_gid() if the group is in multiple hierarchies, each with different owner of tasks file?
