libhugetlbfs
The libhugetlbfs contains a set of functional and stress tests which target specific hugetlbfs bugs which have been since been fixed. This makes it quite a good start for hugetlbfs regression and stress testing. If you have any additional test cases, please consider contributing them to libhugetlbfs so all tests can be maintained together.
libhugetlbfs development snapshots are available at http://libhugetlbfs.ozlabs.org
