There are some new patches and the order goes from cleanups to "obvious wins" towards "just RFC" (last two patches). But it's all theoretical for now, I'm trying to run some tests with the usual problem of not having good workloads and metrics :) But I'd like to hear some feedback anyway. For now this is based on v4.9. I think the only substantial new patch is 08/10, the rest is some cleanups, small tweaks and bugfixes.
