The LTP hugetlb tests are broken. I had earlier suggested to replace
this with the test cases available with the libhugetlbfs releases.
However, we had some problems:
1. We were not sure whether the libhugetlbfs tests all scenarios as
done by the LTP tests,
2. We had no volunteers who can look into this,
So, if somebody is willing to do this:
1. Investigate what exact tests to pick up from LTP,
2. which tests to pickup from libhugetlbfs library,
3. Merge them to the LTP build/install/run system,
It would be nice, and we would be bothered about these failures time and
again :-(
