-What:   namespace cgroup (ns_cgroup)
-When:   2.6.38
-Why:    The ns_cgroup leads to some problems:
-	* cgroup creation is out-of-control
-	* cgroup name can conflict when pids are looping
-	* it is not possible to have a single process handling
-	a lot of namespaces without falling in a exponential creation time
-	* we may want to create a namespace without creating a cgroup
-
-	The ns_cgroup is replaced by a compatibility flag 'clone_children',
-	where a newly created cgroup will copy the parent cgroup values.
-	The userspace has to manually create a cgroup and add a task to
-	the 'tasks' file.
