mm/migrate: correct thp migration stats
PageTransHuge returns true for both thp and hugetlb, so thp stats was counting both thp and hugetlb migrations. Exclude hugetlb migration by setting is_thp variable right. Clean up thp handling code too when we are there. Fixes: 1a5bae25 ("mm/vmstat: add events for THP migration without split") Signed-off-by:Zi Yan <ziy@nvidia.com> Signed-off-by:
