The docstring of Controller.move_all_tasks_to() says that the function
moves all the tasks to the "dest" cgroup. However, it iterates over
self._cgroups, which is a dictionary that is lazily populated when you
call Controller.cgroup(). For example, this doesn't work:
cpuset_cg = target.cgroups.controller("cpuset")
cpuset_cg.move_all_tasks_to("top-app")
Because you haven't populated self._cgroups yet. You need to manually
populate the dictionary with something like:
for group in cpuset_cg.list_all():
cpuset_cg.cgroup(group)
before you can use move_all_tasks_to(). Iterate through
self.list_all() instead of self._cgroups to really move all tasks to
to the destination directory.
Controller.move_tasks() has a try-except block to get the cgroups of
the source and destination groups. Controller.cgroup() caches the
groups in self._cgroups and populates it if it hasn't been already.
Simplify move_tasks() and let it deal with source and dest cgroups
that exist but the controller hasn't loaded yet.
