Yes, it's definitely a cool idea. I think the current implementation is not that useful, since it jams all the unrelated kernel locks into a single ordered list, when in fact many locks simply have no ordering relationship at all because they're never both taken. This makes the list hard to read and in fact loses the information of which locks have been taken together.
