H A Dvmemmap_dedup.rstdiff dff033818a06e7d0bf79271e34bda11c2d9d98d0 Tue Jun 28 04:22:30 CDT 2022 Muchun Song <songmuchun@bytedance.com> mm: hugetlb_vmemmap: introduce the name HVO

It it inconvenient to mention the feature of optimizing vmemmap pages
associated with HugeTLB pages when communicating with others since there
is no specific or abbreviated name for it when it is first introduced.
Let us give it a name HVO (HugeTLB Vmemmap Optimization) from now.

This commit also updates the document about "hugetlb_free_vmemmap" by the
way discussed in thread [1].
