cgroup: fix lockdep warning in debug controller
The debug controller grabs cgroup_mutex from interface file show functions which can deadlock and triggers lockdep warnings. Fix it by using cgroup_kn_lock_live()/cgroup_kn_unlock() instead. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Waiman Long <longman@redhat.com>
