As long as add_gd_partition is not changed to add_gd_partition (unsigned, unsigned), /proc/partitions will keep showing negative numbers.

will not be driven by fear into an age of unreason, if we dig deep in
our history and our doctrine, and remember that we are not descended

associate and to defend causes that were, for the moment, unpopular."
