Because: There's no contradiction between improving our local testing and allowing to merge early to expose to the wider testing. The merge early is a part of what makes mm community welcoming as opposed to tip's policy "only 100% perfect material goes in". > - We've become a bit notorious for breaking linux-next I don't think only mm breaks linux-next :) > - It makes it more difficult for us to yank things git rebase -i > - It blurs the line between the stable branch (which in the new model we will be > updating constantly rather than right at the end) and some 'unknown state' of > 'whatever we just sent to linux-next'. The aggregate "next" going to linux-next can include both, stable and stabilizing parts. Or they can go as separate branches. > Cheers, Lorenzo -- Sincerely yours, Mike.
