To set a dasd online dasd_change_state is called twice. The first cycle will schedule initial analysis of the device, set the rc to -EAGAIN and will not touch the device state any more. The initial analysis will in turn call dasd_change_state to increase the state to the final DASD_STATE_ONLINE. If the dasd_change_state on the second thread outruns the other one both finish with the state set to DASD_STATE_ONLINE and the device refcount will be decreased by 2. Fix this by leaving dasd_change_state on rc == -EAGAIN so that the refcount will always be decreased by 1.
