Ugh. According to these numbers, the latest sched-numa actually regresses against mainline on Specjbb. No way is this even close to ready for merging in the 3.8 timeframe. I would ask the invilved people to please come up with a set of initial patches that people agree on, so that we can at least start merging some of the infrastructure, and see how far we can get on at least getting *started*. As I mentioned to Andrew and Mel separately, nobody seems to disagree with the TLB optimization patches. What else? Is Mel's set of early patches still considered a reasonable starting point for everybody?
Mel's infrastructure patches, 1-14 and 17 out of his latest series, could be a great starting point. Ingo is trying to get the mm/ code in his tree to be mostly the same to Mel's code anyway, so that is the infrastructure everybody wants. At that point, we can focus our discussions on just the policy side, which could help us zoom in on the issues. It would also make it possible for us to do apple to apple comparisons between the various policy decisions, allowing us to reach a decision based on data, not just gut feel. As long as each tree has its own basic infrastructure, we cannot do apples to apples comparisons; this has frustrated the discussion for months. Having all that basic infrastructure upstream should short-circuit that part of the discussion. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
