David Rientjes 215ba78115 mm, selftests: test return value of munmap for MAP_HUGETLB memory ... When MAP_HUGETLB memory is unmapped, the length must be hugepage aligned, otherwise it fails with -EINVAL. All tests currently behave correctly, but it's better to explcitly test the return value for completeness and document the requirement, especially if users copy map_hugetlb.c as a sample implementation.
