Stefan Weinhuber 33b62a30f7 [S390] dasd: automatic recognition of read-only devices 
In z/VM it is possible to attach a device as read-only. To prevent
unintentional write requests and subsequent I/O errors, we can detect
this configuration using the z/VM DIAG 210 interface and set the
respective linux block device to read-only as well.
