Subject: [PATCH 08/16] libiscsi: use cls_session as argument for target and session reset
Date: Tue, 17 Oct 2023 12:07:21 +0200 [thread overview]
Message-ID: <20231017100729.123506-9-hare@suse.de> (raw)
In-Reply-To: <20231017100729.123506-1-hare@suse.de>
iscsi_eh_target_reset() and iscsi_eh_session_reset() only depend
on the cls_session, so use that as an argument.
