Subject: [PATCH 06/25] ibmvscsi_tgt: Convert to new submission API
Date: Sat, 27 Feb 2021 10:59:47 -0600 [thread overview]
Message-ID: <20210227170006.5077-7-michael.christie@oracle.com> (raw)
In-Reply-To: <20210227170006.5077-1-michael.christie@oracle.com>
target_submit_cmd is now only for simple drivers that do their
own sync during shutdown and do not use target_stop_session. It
will never return a failure, so we can remove that code from
the driver.
