I prefer to add things to that rather than a debugfs as it is run during boot. IMO it is usual useful to debug things that cause boot issue most of the time. I am not against this so I will leave it to the maintainers. -- Regards, Sudeep _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
