Those are refactoring [1,2] or a very minor fix [3] that doesn't really impact users. Those are not built in porting-friendly way because those were not meant to be hotfixes. To port those, no small amount of refactoring or porting of more dependencies are expected. I don't mind porting non-Cc: stable@ DAMON patches to stable kernels. And I'm happy to help doing that. But I'm not quite sure if this is indeed what you want, or picked by a mistake. Could you please confirm?
