Well the difference between MPOL_DEFAULT and MPOL_LOCAL may be confusing.
Mention somewhere in the MPOL_LOCAL description that the policy with
MPOL_DEFAULT reverts to the policy of the process and MPOL_LOCAL to try to
allocate local? Note that MPOL_LOCAL also will not be local if it just
happens that the local node is overallocated. This is usually confusing
for newcomers. The node/zone reclaim must be activated in order to allow
node local reclaim that results in a node local allocation.
