Mike Kravetz 692b55815c userfaultfd/selftests: clean up hugetlb allocation code ... The message for commit f5c7329718 ("userfaultfd/selftests: fix hugetlb area allocations") says there is no need to create a hugetlb file in the non-shared testing case. However, the commit did not actually change the code to prevent creation of the file. While it is technically true that there is no need to create and use a hugetlb file in the case of non-shared-testing, it is useful. This is because 'hole punching' of a hugetlb file has the potentially incorrect side effect of also removing pages from private mappings. The userfaultfd test relies on this side effect for removing pages from the destination buffer during rounds of stress testing. Remove the incomplete code that was added to deal with no hugetlb file. Just keep the code that prevents reserves from being created for the destination area.
