Subject[PATCH 15/33] task-containersv11-add-container_clone-interface-cgroups-fix-refcount-bug
Updates cgroup_clone() to use lookup_one_len() rather than
cgroup_get_dentry(). Originally part of
task-cgroupsv11-basic-task-cgroup-framework-cgroups-fix-refcount-bug
but split out by akpm for the -mm tree.
