It has some tests I ran along with tracing that detected issues. Of course,
everything needs to be run with lockdep enabled too.  

I did run with lockdep (and some custom hacky state tracking) but
forcing migration is a hole in my test coverage.

Is there a particular test you're suggesting?

I think I mostly did:

  $ while true; do rtla timerlat top -u -q & PID=$!; sleep 5;

or variations of it. IIRC, that would cause a lockdep splat here or
there.
