This is You don't have anywhere near the level of testing that you'd need to cover what the bot is trying to pull in, the subsystem and driver coverage is extremely thin relative to the enthusiasm with which things are being picked up. All the pushback I see in review is on me for being conservative about what gets pulled into stable and worrying about interactions with out of tree code. > a sign that things are working, it's just that some SoC trees are slower > than mainline by a few months, and that's fine.

If we want to encourage people to pull in stable we should be paying attention to that sort of stuff.
