what matters is that only items should be displayed that i _can_ fix.
With v8 i was able to make kernel/sched*.c almost noise-free, but with
v9 and v10 that's not possible anymore. And the moment the default
output of the tool cannot be made 'empty', we've lost the biggest

And this is not about any particular false positive. I dont mind an
"advanced mode" non-default opt-in option for the script, if someone is
interested in borderline or hard to judge warnings too, but these
default false positives are _lethal_ for a tool like this. (and i made
