Hi,
I still think it is a issue. Perhaps above changelog is unclear. Further
explain is as follows.
when hugetlb_pages is disable and arch_want_huge_pmd_share is enable, we
maybe call
huge_pmd_sahre in hugetlbpage.c, but the function actually is not definition
as it is not
exported. is it right ??
Thanks
