I find the term "vmemmap deduplication" more self-explanatory (at least for me) to refer to your technique ,and similarly s/optimize/dedup. Or vmemmap tail page deduplication (too verbose maybe) because really that's what this optimization is all about. OTOH it would slightly deviate from what maybe established now in hugetlb code.
