Johannes Weiner 2443462b0a mm: move pagevec stripping to save unlock-relock ... In shrink_active_list() after the deactivation loop, we strip buffer heads from the potentially remaining pages in the pagevec. Currently, this drops the zone's lru lock for stripping, only to reacquire it again afterwards to update statistics. It is not necessary to strip the pages before updating the stats, so move the whole thing out of the protected region and save the extra locking.
