I wonder if we could extend kernel-doc (not your preferred option as
it seems) for a new dedicated warning message or maintain a separate
kernel-doc sanity checking script to emit a dedicated warning based on
some heuristics that suggests when a "header comment" is probably
unintentionally declared as a "kernel-doc comment" when it really
should not be.

Jonathan, would you then prefer to have a separate kernel-doc sanity
checking script that then allows us to maintain checking for patterns
we already cleaned up?

Having a warning in kernel-doc for "This comment starts with /** but
isn't a kerneldoc comment" could be useful, I guess.  That is the real
problem, not the fact that it appears at the top of the file.  I'm all
for tools that help us to clean things up, but let's not add
line-counting hacks to try to paper it over.

Yeah, and as this line-counting is really just a poor man's
heuristics, we might just be better to really turn this heuristics
into a dedicated cleanup warning script, then we can check for more
indicators, such as "does it contain the word Copyright" somewhere in
the kernel-doc comment, which tells us even more that this is not a
kernel-doc as we would expect it.

Aditya, would you like to try to turn this check into a separate script instead?

Lukas
