Thanks for replying Daniel. I agree with your reasoning but we're looking at the problem from two different perspectives. It's not silly to require review per se. My patches also deserves review but the problem is that I cannot count on getting it and I don't think I should be stealing time from others (you included) who's time is better spent elsewhere. Currently I get to choose between bad (patches without good review) or worse (no patches at all). Unfortunately I cannot pick bad because of the r-b tag requirement. Also, I review gma500 patches because it is expected of me and because I can. Not because I think the quality is worse than mine. I'd love to get reviews back but so far people just drop their patches and run. > > That's why drm-intel, drm-misc and anything else I'll ever maintain > will have a hard&solid rule to never push my own stuff (or anyone else > with commit rights) without review. No exceptions. That works when dealing with i915 and drm core (and other bigger drivers). You have a decent group of people who are technically qualified with personal and professional incentives to review your patches. It's easy to have high standards when they are not being challenged. On the gma500 team there's me and a bunch of frustrated users. What I would like to do is to continue shrinking the codebase and fix up the most obvious mistakes to make it more maintainable and let it live a couple of more years. I will likely have some time to do that again soon. Not because it's very important but because it's fun and makes a small group of people happy. Adding a bunch of process to this makes it less fun and reduces my output. > > In my opinion, as a maintainer of a part of the linux kernel your job > is to be the steward of the code and contributors/community around it, > not be the lord with special priviledges like being able to push > unreviewed patches or nacking contributions just because you're the > maintainer.

Right now I'm the lord of a mess but with less privileges than the contributors. They at least get their patches reviewed and included. Sounds more like I'm the fool ;) Sure, I can nack peoples patches but where's the fun in that. Nacking is never the easy choice since it requires justification and thus more work. I certainly don't see it as a privilege. > > So at least from my side, yes there's an agenda behind this all, and > its intentional. It also seems to work reasonable well thus far, since > worst case drm-misc maintainers serve as reviewers of last resort. I understand there's an agenda and it makes sense from a "big drivers" pov. After some thinking, I would prefer the "pull from layers of trust" approach instead of "push through a very tightly tuned process". The layers of trust model also works well (as we all know). If maintainers feel they are getting overwhelmed with work we should look at expanding the subsystem tree instead of inventing new ways to handle things. Perhaps the solution to all of this is to just go back to sending patches for small drivers as pull-requests to you or Dave and let you decide if the sender is trustworthy enough to deserve a signed-off-by. Either way, I don't want to turn this into a long discussion. If this is the way it needs to work then that is fine by me. Most of the time it works and gma500 is the driver with the smaller userbase and should not make life difficult for the bigger drivers.
