    mm: vmscan: move direct reclaim wait_iff_congested into shrink_list · 8e950282
    Mel Gorman authored
    shrink_inactive_list makes decisions on whether to stall based on the
    number of dirty pages encountered.  The wait_iff_congested() call in
    shrink_page_list does no such thing and it's arbitrary.
    
    This patch moves the decision on whether to set ZONE_CONGESTED and the
    wait_iff_congested call into shrink_page_list.  This keeps all the
    decisions on whether to stall or not in the one place.
