Subject: [RHEL7 PATCH 06/31] tests: map-high-truncate-2: Skip if truncation
point is not aligned
Attempting ftruncate() on a hugetlbfs file descriptor requires
the truncation point to be aligned to the huge page size. So,
this test is not applicable for huge page sizes greater that
are either greater than or not a factor of the truncation point.
