Well, it doesn't help that most of the stable emails aren't sent to the subsystem's mailing list, but instead just to the individual people mentioned in the commit.

You've said in the past that sometimes you'd like to backport a commit even if the maintainer objects and/or it is known buggy. https://lore.kernel.org/stable/d91aaff1-470f-cfdf-41cf-031eea9d6aca@xxxxxxxxxxx also didn't explicitly say "Don't backport this" but instead "This patch has issues", so maybe that made a difference? Anyway, the fact is that it happened. And if it happened in the one bug that I happened to look at because it personally affected me and I spent hours bisecting, it probably is happening in lots of other cases too. So it seems the process is not working... Separately from responses to the AUTOSEL email, it also seems that you aren't checking for any reported regressions or pending fixes for a commit before backporting it. Simply searching lore for the commit title https://lore.kernel.org/all/?q=%22drm%2Famdgpu%3A+use+dirty+framebuffer+helper%22 would have turned up the bug report https://lore.kernel.org/dri-devel/20220918120926.10322-1-user@am64/ that bisected a regression to that commit, as well as a patch that Fixes that commit: https://lore.kernel.org/all/20220920130832.2214101-1-alexander.deucher@xxxxxxx/ Both of these existed before you even sent the AUTOSEL email! So to summarize, that buggy commit was backported even though: * There were no indications that it was a bug fix (and thus potentially suitable for stable) in the first place. * On the AUTOSEL thread, someone told you the commit is broken. * There was already a thread that reported a regression caused by the commit. Easily findable via lore search. * There was also already a pending patch that Fixes the commit. Again easily findable via lore search. So it seems a *lot* of things went wrong, no? Why? If so many things can go wrong, it's not just a "mistake" but rather the process is the problem... - Eric
