Might be good to revisit:
https://docs.kernel.org/process/stable-kernel-rules.html

And, assuming you feel like it still might be needed, you might add
some annotation before your signed-off-by line to clarify your
motivation for submitting it, ie: how it "fix[es] a real bug that
bothers people".

Adding tracepoints definitely feels more like a feature, not a bug fix.
