Scrap that. I don't think we can fail css_online for the root css in 3.13-fixes and this would cause conflict with 3.14, so let's not commit it to 3.13-fixes. Vladimir, can you please respin the patch on top of cgroup/for-3.14 but make cgroup_unload_subsys() check whether css is actually there before calling offline so that it matches the usual offline path better?
