Subject: [PATCH 07/25] qla2xxx: Convert to new submission API
Date: Wed, 17 Feb 2021 14:27:53 -0600 [thread overview]
Message-ID: <20210217202811.5575-8-michael.christie@oracle.com> (raw)
In-Reply-To: <20210217202811.5575-1-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.
tcm_qla2xxx uses target_stop_session to sync session shutdown with lio
core, so we use target_init_cmd/target_submit_prep/target_submit, because
target_init_cmd will detect the target_stop_session call and return
an error.
