    I talked a little about this with Peter Zijlstra on IRC, and we agreed
    that we'll keep this as is until we notice that kernel developers are
    still confused with the output.

    The more advanced I make this output, the more likely I'll make a
    mistake and show something that is not what actually happens. I wrote a
    module to trigger each of these cases and the problems that lockdep can
    detect grows exponentially as we make the output more specific.

    I probably should modify the lockdep selftests to add an option to show
    the output as well as it triggers errors. This would allow me to make
    sure the output still works.

    But for now, I have other things to work on ;)
