Hi Daniel and Jani and other members of the i915-commit-cabal, I've mentioned this a few times to Daniel in the past (like at the last kernel summit), but the way you all are handling the tagging of patches for inclusion in stable kernel releases is totally broken and causing me no end of headaches. It's due to your "you have a branch, you have a branch, you all have a branch!" model of development. You have patches that end up flowing in to Linus's trees multiple times for different releases. Now git is smart enough to handle most of this, and you end up doing a lot of hand-fixing for other merge issues, but when it comes to doing the stable kernel work, none of that means squat. All I get to see is when a patch lands in Linus's tree, and if that patch has a "cc: stable@" marking, then I look at it. But, when a patch hits Linus through multiple branches, that means I see it multiple times, usually months apart in timeframe. This is especially bad during the -rc1 merge window when all of the old work you all did for the past 3 months hits Linus, which includes all of the old bugfixes that were already in the previous kernel release. I think there were over 25 different patches in -rc1 that hit this issue. Maybe more, maybe less, I don't know, I'm giving up at this point, I wasted over 2 hours trying to figure out a way to do this in an automated way, or by hand, or something else to deal with all of these rejections or "fuzz merge" which really was a duplicate. And the joy of your "cherry-picked from 12345..." messages, with git commit ids that are no where to be found in Linus's tree at all, is totally annoying as well, why even have this if it doesn't mean anything? I sure can't use it. Not to mention all of the build-breakages, and normal "fails to apply" that you all end up with, your driver subsystem has the largest instance of those as well, and build-breakages are the worst, as they cause my process to come to a screeching halt while I have to bisect to find the broken patch. Given the lack of patches that people actually send me when I send in the "FAILED" emails, I'm guessing that you all don't care that much about stable kernels either, which is fine, as again, I'm giving up on your driver. So, either you all only mark a patch _ONCE_. Or come up with some way for me to determine, in an automated way that a patch is already in Linus's older release, or just don't mark anything and send me a hand-curated list of git commit ids, or patches in mbox form (like DaveM does), or something else you all come up with. What is happening now is not working at all, and as of now, I'm going to just drop all i915 patches with a cc: stable marking on the floor. Congrats on being the first subsystem that I've had to blacklist from my stable patch workflow :( greg "35k feet above India and grumpy" k-h
