hmm... I think if we start doing that we would make quite a mess of
documentation in the kernel. Also note its a warning stating "possible
unneceessary" - so I would not see the necessity.

At most I would include a note on this in the commit message so that
anyone checking the origin would see that this is intenttional - assuming
that people modifying code would be using git blame to locate the
origin of any code...
