Ouch.  At least compared to the current kernel your patch is wide
of the mark of what is needed to use mm->memcg correctly.

I have however written my own and if someone can review it I would
really appreciate it.  It looks like we can change mm->owner to
mm->memcg without too much trouble and reduce the amount of code
in the kernel at the same time.
