Revision 33b62a30f78536b976183cc764c08038ac011e0a authored by Stefan Weinhuber on 08 March 2010, 11:26:24 UTC, committed by Martin Schwidefsky on 08 March 2010, 11:26:27 UTC
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.
