[S390] cio: introduce notifier for boxed state
If a ccw device did not respond in time during internal io, we set it into boxed state. With this patch we have the following behaviour: * the ccw driver will get a notification if the device was online and goes into the boxed state * if the device was disconnected and got boxed nothing special is to be done (it will be handled in reprobing later) * if the device got boxed while initial sensing it will be unregistered Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
