    mm: vmscan: remove dead code related to lumpy reclaim waiting on pages under writeback · a18bba06
    Mel Gorman authored
    Lumpy reclaim worked with two passes - the first which queued pages for IO
    and the second which waited on writeback.  As direct reclaim can no longer
    write pages there is some dead code.  This patch removes it but direct
    reclaim will continue to wait on pages under writeback while in
    synchronous reclaim mode.
