Date: Mon, 6 Feb 2012 12:19:29 -0800 Message-Id: <1328559569-10783-1-git-send-email-yinghan@google.com> Sender: owner-linux-mm@kvack.org List-ID: To: Michal Hocko , Balbir Singh , Rik van Riel , Hugh Dickins , Johannes Weiner , Mel Gorman , KAMEZAWA Hiroyuki , Pavel Emelyanov Cc: linux-mm@kvack.org In v3.3-rc1, the global LRU has been removed with commit "mm: make per-memcg LRU lists exclusive". The patch fixes up the memcg docs. I left the swap session to someone who has better understanding of 'memory+swap'.
