There hasn't been nearly enough review or testing of this patch series yet. Before a merge, it needs to be split up in smaller, more digestable chunks for more comprehensive review, regression testing and behavioural analysis. There's probably only a handful of people who have done any testing on the patchset so far, and given the widespread changes it needs a lot more testing than this before we should consider merging any of it. I really want to see this move forward too, but it changes lots of critical infrastructure in subtle ways and so, IMO, this is not a patchset we should be gung-ho about.
