[PATCH RFC 0/2] cgroup/mem: add a node to double charge in memcg

[Eric Chanudet]

It was suggested previously[1] to introduce a knob for dmem region to
double charge dmem and memcg at the will of the administrator.

This RFC tries do that in the dmem controller through the cgroupfs
interface already available and walk through the problems that creates.
