Ingo & Peter, This patchset was discussed spread and deeply. Now just 6th/8th patch has some arguments on them, Paul think it is better to consider blocked_load_avg in balance, since it is helpful on some scenarios, but I think on most of scenarios, the blocked_load_avg just cause load imbalance among cpus. and plus testing show with blocked_load_avg the performance is just worse on some benchmarks. So, I still prefer to keep it out of balance. http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg455196.html Is it the time to do the decision or give more comments?
