I haven't looked at the swap accounting at all yet, sorry. But where
did this discussion go all of a sudden? :-)

That array is not allocated at all when the memory controller is
disabled at boot-time.

Rather, we have those mem_cgroup_disabled() conditionals everytime we
enter the memory controller from the VM and the idea is to patch them
out during boot, since you can not re-enable the thing anyway.
