Gack, I posted the slightly wrong version. This version prevents lumpy reclaim ever being used. The figures I posted were for a patch where this condition looked like
if (COMPACTION_BUILD && priority > DEF_PRIORITY - 2) sc->lumpy_reclaim_mode = LUMPY_MODE_COMPACTION; else sc->lumpy_reclaim_mode = LUMPY_MODE_CONTIGRECLAIM;
