I'm not convinced yet. I addressed this already. I suggested to add a "raw" variant that turns to a nop when LOCKDEP is not enabled. That is, for those locations that are only for working with LOCKDEP, the call will be: lockdep_init_map_raw() This will differentiate the locations that are for just lockdep and those that are for both lockdep and tracing. -- Steve
