Subject: [PATCH] Per-NUMA control of huge pages
There are two new features of hugetlb related to NUMA:
Interaction of Task Memory Policy with Huge Page Allocation/Freeing and
Per Node Hugepages Attributes. Please refer to
Documentation/vm/hugetlbpage.txt in kernel source for details. This
patch try to verify those two features in numa's test.
v1->v2: avoid using 'eval' and '{$..#..}'.
