So, you really want to see 20+ KERNEL WARNINGS in your system when you boot without CONFIG_DEBUGFS enabled? No, that's not ok at all, sorry, that is not going to happen. Running a kernel without debugfs is a valid state, you are treating it as an error, which isn't ok. greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
