[stgt] [PATCH 1/1] Add support for READONLY disk devices

[ronnie sahlberg]

List

Please find attached a patch that adds a new lun parameter : readonly.


Add a new device parameter "readonly={0|1}" that when set to !0 makes
the device read-only.

For DISK devices, this is communicated back to the initiator by
setting the WP bit in teh device specific byte in the mode sense
header.
It will also fail any WRITE6/10/12/16 calls with a
DATA_PROTECT/ASC_WRITE_PROTECT

The manpage for tgtadm has been expanded with a PARAMETERS section and
the readonly parameter is added as the first parameter for this
section.
