Subject: [PATCH v2 2/5] scsi: target: drop xcopy DISK BLOCK LENGTH debug
Date: Thu, 26 Mar 2020 23:15:02 +0100 [thread overview]
Message-ID: <20200326221505.5303-3-ddiss@suse.de> (raw)
In-Reply-To: <20200326221505.5303-1-ddiss@suse.de>
The DISK BLOCK LENGTH field is carried with XCOPY target descriptors on
the wire, but is currently unmarshalled during 0x02 segment descriptor
passing. The unmarshalled value is currently unused, so drop it.
