OK, do you see why this is a false positive?  And why asking the
thousands of people "in the commmunity" to all do exactly the same
evaluation is a massive waste of time?

And why people, after doing a quick evaluation to determine that the
very first warning you sent out (which was repeated multiple times in
your log; you didn't even bother to winnow out duplicate warnings)
is a false positive, might be inclined to ignore all e-mails from
you "asking for help" in the future?

Look, it's good that you're being enthusiastic.  But you need to do
more than just send screen shots of a kernel bugzilla where it's
already been explained to you that darned few people care about the
open/closed statistics, or running builds to complain about warnings.

If you want to send a patch to clean up the warning, figure out how to
do that, and then to send the to the right people.  (Hint: reading the
Documentation/SubmittingPatches and Documentation/Submitchecklist
files.)
