[S390] dasd: do path verification for paths added at runtime
When a new path is added at runtime, the CIO layer will call the drivers path_event callback. The DASD device driver uses this callback to trigger a path verification for the new path. The driver will use only those paths for I/O, which have been successfully verified. Signed-off-by: Stefan Weinhuber <wein@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
