OK.. This looks harder than I thought, it needs some debugging. I
looked at your code and logs and have some questions
1. I presume this line
err = cgroup_get_cgroup(group0); fails for you
2. Your cgroup_config_load_config() has succeeded, which I thought was
the original problem. If this step did succeed, what wa the mount
hierarchy it created?
a. I can see a reference to CPU/FREEZER being mounted together and
groups rw/realtime/.. within that
3. Your sample seems to add more controllers than those that are mounted
For step1, I would recommend freeing group0 after creation and do a
cgroup_new_cgroup("grp_0"), don't add any controllers, then try to get
the cgroup with the API
