I know that you're trying to help us, but this tool needs to be far
better than Lockdep before we should think about merging it.  Even if
it finds 5% more potential deadlocks, if it creates 95% more false
positive reports --- and the ones it finds are crazy things that
rarely actually happen in practice, are the costs worth the benefits?
And who is bearing the costs, and who is receiving the benefits?

I personally believe that there's potential that this can be helpful and we
will want to merge it.

But, what I believe Ted is trying to say is, if you do not know if the
report is a bug or not, please do not ask the maintainers to determine it
for you. This is a good opportunity for you to look to see why your tool
reported an issue, and learn that subsystem. Look at if this is really a
bug or not, and investigate why.

I agree with Steven here, to the point where I'm willing to invest some
time being a beta-tester for this, so if you focus your efforts on
filesystem/mm kinds of problems, I can continue looking at them and
tell you what's helpful and what's unhelpful in the reports.
