The best practice is to have upstream patches that can apply cleanly to
LTS kernels.

- One patch that can be backported for the fix, one or more for
  clean-ups that apply only to master;

- Identify pre-requisites that need to be backported first to make
  your fix apply cleanly; or

- Handcraft the fix for each LTS kernel

Post an RFC here, let's see what you're thinking.
