The 5.10 backport itself looks fine, but I can't take it on its own: 1e988c3fe126 is still missing from 6.6.y and 6.12.y (it's present in 7.0, 6.18, 6.1 and 5.15), and we don't add a fix to an older tree while a newer one is missing it. Once 6.6.y and 6.12.y carry it, I'll queue the 5.10 backport. -- Thanks, Sasha
