Revision e0c23279c9f800c403f37511484d9014ac83adec authored by Mel Gorman on 01 November 2011, 00:09:33 UTC, committed by Linus Torvalds on 01 November 2011, 00:30:50 UTC
If compaction can proceed, shrink_zones() stops doing any work but its callers still call shrink_slab() which raises the priority and potentially sleeps. This is unnecessary and wasteful so this patch aborts direct reclaim/compaction entirely if compaction can proceed.
