Subject: [PATCH v4 1/3] nvmet_execute_identify_ctrl: don't overwrite with 0-bytes
Date: Mon, 14 Aug 2017 22:12:37 +0200 [thread overview]
Message-ID: <20170814201239.15255-2-mwilck@suse.com> (raw)
In-Reply-To: <20170814201239.15255-1-mwilck@suse.com>
The merged version of my patch "nvmet: don't report 0-bytes in serial
number" fails to remove two lines which should have been replaced,
so that the space-padded strings are overwritten again with 0-bytes.
Fix it.
Fixes: 42de82a8b544 nvmet: don't report 0-bytes in serial number
Signed-off-by: Martin Wilck <mwilck@suse.com>
