It looks like the regression is 407d1a51921e, which appeared in v6.6, almost a year ago, so it's fairly old. What target are you thinking about for the V1 patch? I guess if we add it as a v6.11 post-merge window fix, it might get backported to stable kernels before v6.11? But if the plan is to merge the V1 patch and then polish it again before v6.11 releases, I'm not sure it's worth the churn. Bjorn
