If a page is on a pagevec then it is !PageLRU and mark_page_accessed()
may fail to move a page to the active list as expected. Now that the
LRU is selected at LRU drain time, mark pages PageActive if they are
on a pagevec so it gets moved to the correct list at LRU drain time.

If a page is on a pagevec then it is !PageLRU and mark_page_accessed()
may fail to move a page to the active list as expected. Now that the
LRU is selected at LRU drain time, mark pages PageActive if they are
on a pagevec so it gets moved to the correct list at LRU drain time.
