I tend to agree. unlikely anyone backports printk message updates. I have quickly glanced through stable-4.9 and haven't seen such backports. well, may be there are some. can tweak the warning a bit, probably. e.g. "if you are planning to backport your change to kernels older than 4.14 then ignore this warning". but not sure if it's worth it. -ss
