All patches developed to fix a bug or add/improve new/existing functionality should be submitted to upstream first. The Ubuntu kernel maintainers prefer that these patches come to Ubuntu kernel though upstream. But for any reason you wish to submit a sauce or config patch to the ubuntu kernel mailing list, please follow the process below.
Use the appropriate commit template when you commit your changes.
- Use git format-patch -1 to generate your patch file.
- After you push your changes to your remote git tree use git request-pull to generate a pull request.
Submit your patch with a request pull message to the Ubuntu Kernel Mailing list. Ubuntu Kernel Team <email@example.com>
