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.
