cgroup: grab cgroup_mutex earlier in cgroup_subtree_control_write() Move cgroup_lock_live_group() invocation upwards to right below cgroup_tree_mutex in cgroup_subtree_control_write(). This is to help the planned locking simplification. This doesn't make any userland-visible behavioral changes. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Li Zefan <lizefan@huawei.com>
