> and CONFIG_DYNAMIC_DEBUG, no -DDEBUG required Yes, i understand. Till now we had this enabled, so pr_debug works just fine, but now it is disabled hence the question. Also there are pros and cons to having control using dyndbg, user can disable dyndbg, there be missing imp debugs, in this case having module level (-DDEBUG) helps but if we want entire system to run in non-debug mode, disabling dyndbg helps. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
