One more cgroup code review detail ...
The following is evidence of some more stale comments in
kernel/cpuset.c. Some routines which used to be in that file, but
which are now reimplemented in cgroups, are still named in cpuset.c

Oh, absolutely. I just refrained from changing them in the rename

Yes, there are such cases.
If tasks are running in a cpuset, and someone changes the
'cpus' of that cpuset, the tasks already in that cpuset d

Cgroup (aka container) code review:
Except for the very last item below, my other comments are minor.
And the last item is pretty easy too - just more important.
Overall - nice stuff. I like this generalization of the cpuset
hierarchy. Thanks.

Review comments on Documentation/cgro
Add the per-directory "tasks" file for cgroupfs mounts; this allows the
user to determine which tasks are members of a cgroup by reading a
cgroup's "tasks", and to move a task into a cgroup by writing its pid to
its "tasks".
