No. The rules for stable is that a patch must really fix something and be minimal. Documentation/process/stable-kernel-rules.rst What might be best is to develop a minimal, but ugly patch for stable. Get it applied. Around a week later, net will be merged into net-next. You can then have a 'revert' patch, followed by this series making it nice and clean. Andrew
