    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.
