Then you can comment how we estimate sharers by looking at into how many page tables the first subpage is currently mapped, and assume the same holds true for the other subpages. Vote for 'folio_estimated_sharers()'. If better method other than checking mapcount is found in the future, it's easy to update the implementation without change the API name. Regards Yin, Fengwei
