I'm not trying to change the workflow here, I think all this amounts to is just a quality of life improvement for Linus who could ideally merge faster if he knows that the pull requests he's looking at will build and won't brick his laptop. If we start playing games around "must spend X days in linus-next", then yes - I agree with you. -- Thanks, Sasha
