[Bug 693594] Re: cgroup-bin should not move kthreadd into a default cgroup

[Rioting_Pacifst]

This bug has quite a few nasty symptoms (breaks suspend on SMP machines,
etc) and I guess cgroups are going to get more popular as people try the
"superpatch" so could we get one of the following into 12.04 please:

1)do not move all tasks into a default cgroup 
comment CREATE_DEFAULT=yes out and uncomment CREATE_DEFAULT=no in /etc/default/cgconfig

2)putting the following in /etc/cgconfig.conf
group sysdefault {
    cpu {
        cpu.rt_runtime_us = 950000;
    }
}

3) Add a rule so that [kthreadd] is never put in the default group

4) Changing startup script to not move ktreadadd

I think creating a superflous default group is stupid anyway so the
first fix is by far the best.

Upstream have also release 0.38 but nothing in the changelog seems
relevant.
