This discussion seems to imply that I reported a false positive... is
it *known* that I reported a false positive, or is it only a strong
possibility?

Assuming it's a false positive: Since this stops the tracer, it means
that if an actual deadlock possibility is detected later [I'm assuming
that detection of those doesn't get shut down by the bad-lock-ordering
detection either], useful information could be missing from
/proc/latency_trace, if I am not mistaken. Perhaps this could impede
lockdep testing for people running reiser4 filesystems. I guess this
is just a theoretical possibility at this point, but perhaps it's
worth mentioning.
