Everyone makes silly mistakes and your reputation of immunity isn't a
general knoweldge.  Don't be snippy with people trying to help you.

Li is right that that message can only be triggered by
cgroup_disable_mask which can only be set through "cgroup_disable="
kernel boot parameter.

* If you can, add printk of cgroup_disable_mask in cgroup_init() and
