My intention (hopefully the code matches this) is that mbind nodes are
constrained to fit in the cpuset. If you ask to mbind more nodes, those
outside the cpuset are masked off. If you later change the cpuset, then
we mask more nodes off to continue to fit in the cpuset. If this gets us
down to an empty mbind list, then you get to use whatever memory nodes are
in your new cpuset.
