In this case, it's not subjective because checkpatch is clearly not
working as intended.
I don't feel like "checkpatch clean" is a useful criteria for applying
patches. If someone sends a patch and I can spot a bunch of checkpatch
issues with my bare eyeballs then I get slightly annoyed for wasting my
time. But as a reviewer, I mostly care about my own judgement. Can I
understand what the code is doing? It is subjective, but I'm smarter
than a Perl script and I try to be kind to people.
The other things about warnings is that I always encourage people to
just ignore old warnings. If you're running Smatch and you see a
warning in ancient code that means I saw it five years ago and didn't
fix it so it's a false positive. Old warnings are always 100% false
positives.
regards,
dan carpenter
