Kirill A. Shutemov b6ec57f4b9 thp: change pmd_trans_huge_lock() interface to return ptl ... After THP refcounting rework we have only two possible return values from pmd_trans_huge_lock(): success and failure. Return-by-pointer for ptl doesn't make much sense in this case. Let's convert pmd_trans_huge_lock() to return ptl on success and NULL on failure. Signed-off-by: Kirill A.
