The patch titled

mm-use-pagevec-to-rotate-reclaimable-page-kill-redundancy-in-rotate_reclaimable_page.patch
This patch was dropped because it was folded into mm-use-pagevec-to-rotate-reclaimable-page.patch

Subject: kill redundancy in rotate_reclaimable_page
From: Hugh Dickins <hugh@xxxxxxxxxxx>
a.k.a. mm-use-pagevec-to-rotate-reclaimable-page-cleanup.patch
PageActive and PageLRU twice in a row: of course there used to be a
lock taken in between those tests; but now that pagevec_move_tail() is
making those tests under lock, there's no point to repeating them here.
