Does > it bisect, etc. or just green/red? For linux-next it's just green/red now. We've added it to have an "upstream merge will break bpf" signal, because it happened regularly. For bpf list we run on every incoming patch, so regressions are detected quickly. Not feasible to do that for *every* upstream patch, we'd need much more compute. An auto-bisection is something I thought about, but never got to it. These days with LLMs this may be easier to set up though. > > -- > Cheers, Lorenzo
