In fairness it is perfectly clear, it's just that I never considered calling it without master/admin because why would you ever do that?

FWIW, drm_info does it to display the current buffers metadata. Pretty useful when debugging.

We also have the state debugfs file for this, which should dump everything we can decode. If it doesn't we should extend it there ideally, instead of hand-rolling some tool that users/devs then don't have handy. debugfs tends to be there (at least for developers). -Daniel
