unfortunately 2.4 is not an option either as i am running kernel 3.0.3
which does not provide smp_lock.h
I will be watching DAHLIN-274 for updates.
meanwhile
       if (!parent)
               dev_set_name(dev, "dyn:%d", next_dyn++);
       else
               dev_set_name(dev, "%s:%s", parent->bus->name,
dev_name(parent));

did the job and i have 2 local spans for the tests
