I see.

Perhaps it would make sense to mark these patches as having been selected
automatically?

That way, reviewers would be able to better judge whether a backport makes
sense, as it wouldn't be implied that someone has encountered a problem on a
stable kernel, requiring the backport.

Maybe that was on the cover letter -- I only recieved this patch in isolation.

Thanks,
Mark.
