I mean this is at v9, each doing little changes. It is quite tiresome to barely get to a bookmarked version just to find out that there are 2 new versions out. I am sorry to be grumpy and I can understand some frustration it doesn't move forward that easilly but this is a _big_ change. We should start with a real high level review rather than doing small changes here and there and reach v20 quickly. I am planning to find some time to look at it but the spare cycles are so rare these days... -- Michal Hocko SUSE Labs
