When allocating hugetlbfs pool pages via /proc/sys/vm/nr_hugepages,
the pages will be interleaved between all nodes of the system. If
nodes are not equal, it is quite possible for one node to fill up
before the others. When this happens, the code still attempts to
allocate pages from the full nod

When allocating hugetlbfs pool pages via /proc/sys/vm/nr_hugepages,
the pages will be interleaved between all nodes of the system. If
nodes are not equal, it is quite possible for one node to fill up
before the others. When this happens, the code still attempts to
allocate pages from the full nod
