I'd recommend to look at the v2 of the cpuset controller that implements
the hierarchical behavior among configured memory node sets.

(My comment would better fit to
[PATCH 3/4] numa: introduce numa group per task group
IIUC, you could use cpuset controller to constraint memory nodes.)

For the second part (accessing numa statistics, i.e. this patch), I
wonder wheter this information wouldn't be better presented under the
cpuset controller too.

HTH,
