Another thing you could be doing is not zeroing swapper->nr if the shrinker function doesn't do anything, in order to try to maintain pressure on the dcache. This would be similar to your deferred list idea. But I guess that using 0 order allocations for these GFP_NOFS caches means you would be losing far less dcache pressure in this way, so it might not make much difference. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
