We already have most of logic in place and the only thing missing is how to switch it. Wouldn't something like the following work? * Add a sysctl knob to enable asynchronous device probing on module load and enable asynchronous probing globally if the knob is set. * Identify cases which can't be asynchronous and make them synchronous. e.g. keep who's doing request_module() and avoid asynchronous probing if current is probing one of those.
