The kernel is providing the mechanism to interleave over a set of nodes or prefer a single node for allocations, but it also provides for remapping those to different nodes, without regard to locality or affinity to specific hardware, when the cpuset changes. That's what Choice C is intended to replace: a node means a node so either you get an effected mempolicy over the nodemask you asked for, or MPOL_DEFAULT is used because you lack sufficient access.
