They're starting to smell. The hardware and test rig that actually found the original scalability problem is a bit contended with issues at the moment, so I've been unable to get the original issue reproduced. But, I think the patches should be able to stand on their own. Even in my testing, it's obvious that the shrinker code gets queries (via nr_to_shrink=0) *way* more often than it's actually called upon to shrink things. Even if we have to come back with some more patches than this in the future for the original problem that was found, we should feel confident that this patch set is worthwhile and does some real, quantifiable good on its own. I'll go and immediately test that the first four patches in the series are still behaving themselves in the way that I expect. -- Dave -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
