Mel Gorman 66d52cb7c4 mm: page allocator: reconsider zones for allocation after direct reclaim 
commit 76d3fbf8fb upstream.

With zone_reclaim_mode enabled, it's possible for zones to be considered
full in the zonelist_cache so they are skipped in the future.  If the
process enters direct reclaim, the ZLC may still consider zones to be full
even after reclaiming pages.  Reconsider all zones for allocation if
direct reclaim returns successfully.
