Hugetlb VMAs are not mergeable, that means a VMA couldn't have VM_HUGETLB and VM_MERGEABLE been set in the same time. So we use VM_HUGETLB to indicate new mergeable VMAs. Because of that a VMA which has VM_HUGETLB been set is a hugetlb VMA only if it doesn't have VM_MERGEABLE been set in the same time.
