Absolutely.

As I've stated before, I actually believe the kmemcg-stack and
kmemcg-slab (this one) portions should be merged separately. (So we can
sort out issues more easily, and point to the right place)

The first one is a lot more stable and got a lot more love. The goal of
this one is to get it reviewed so we can merge as soon as we can - but
not sooner.

early v3.8 sounds perfect to me.
