We have a probe thread that checks for new storage devices and adds them to the bus with ps3_system_bus_device_register(), which calls device_register(). I guess the actual bus probe() routine gets called through the notifier call chain? That's where I got lost...No, ->probe() is called from device_register() directly. If you just have one probe thread, you should have enough serialization.
IC, through bus_attach_device() in device_add(). Any chance this will change? I already added a mutex to ps3disk to protect against this.
