cgroup: remove cgroup_root_mutex cgroup_root_mutex was added to avoid deadlock involving namespace_sem via cgroup_show_options(). It added a lot of overhead for the small purpose of it and, because it's nested under cgroup_mutex, it has very limited usefulness. The previous patch made cgroup_show_options() not use cgroup_root_mutex, so nobody needs it anymore. Remove it. Signed-off-by: Tejun Heo <tj@kernel.org>
