I was not actually so much speaking about Con, as about a lot of the tone in general here. And yes, it's not been entirely black and white. I was very happy to see the "try this patch" email from Al Boldi - not because I think that patch per se was necessarily the right fix (I have no idea), but simply because I think that's the kind of mindset we need to have. Not a lot of people really *like* the old scheduler, but it's been tweaked over the years to try to avoid some nasty behaviour. I'm really hoping that RSDL would be a lot better (and by all accounts it has the potential for that), but I think it's totally naïve to expect that it won't need some tweaking too. So I'll happily still merge RSDL right after 2.6.21 (and it won't even be a config option - if we want to make it good, we need to make sure *everybody* tests it), but what I want to see is that "can do" spirit wrt tweaking for issues that come up. Because let's face it - nothing is ever perfect. Even a really nice conceptual idea always ends up hitting the "but in real life, things are ugly and complex, and we've depended on behaviour X in the past and can't change it, so we need some tweaking for problem Y". And everything is totally fixable - at least as long as people are willing to! Linus ---1463790079-1635672683-1174404702=:6730--
