I have no user-visible problem. This is a kind of precaution to confirm that transparent hugepage code should not be called for hugetlbfs workload. .. but I think that this patch doesn't work as I intended because transparent_hugepage_enabled() can return true for vma(VM_HUGETLB). So I separate out this patch from this series for now. Thanks, Naoya Horiguchi -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
