This looks good, however I completely forgot we still had the redundant thing. It was added for cross-release (which has since been reverted) which would generate a lot of redundant links (IIRC) but having it makes the reports more convoluted -- basically, if we had an A-B-C relation, then A-C will not be added to the graph because it is already covered. This then means any report will include B, even though a shorter cycle might have been possible. Maybe we should make the whole redundant check depend on LOCKDEP_SMALL for now.
