Subject: [PATCH 13/40] xen-scsifront: compability status handling
Date: Tue, 27 Apr 2021 10:30:19 +0200 [thread overview]
Message-ID: <20210427083046.31620-14-hare@suse.de> (raw)
In-Reply-To: <20210427083046.31620-1-hare@suse.de>
The Xen guest might run against arbitrary backends, so the driver
might receive a status with driver_byte set. Map these errors
to DID_ERROR to be consistent with recent changes.
