Are all the false positives fixed?
I suspect that to avoid any automation noise, you should just rebase
so that the fixes come first. Otherwise we'll end up wasting a lot of
time on the noise.
This is not that different from introducing new buil;d-time warnings:
the things they point out need to be fixed before the warning can be
integrated, or it causes bisection problems.
