- test_unaligned_start_address_hugetlb
- test_invalid_mode
- test_smallfile_bytemap
- test_smallfile_pfn
- test_smallfile_multientry
- test_largefile_pfn
- test_largefile_pfn_offset
- test_largefile_pfn_overrun
- test_tmpfs_pfn
- test_hugetlb_pfn
- test_largefile_pfn_skiphole
- test_smallfile_pfn_skiphole
