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.
