So what is the actual status of reports these days?

Last time I looked at some reports, it gave a lot of false positives
due to mis-understanding prepare_to_sleep().

For this all to make sense, it would need to not have false positives
(or at least a very small number of them together with a way to sanely
get rid of them), and also have a track record of finding things that
lockdep doesn't.

Maybe such reports have been sent out with the current situation, and
I haven't seen them.
