Subject: [PATCH v3 12/16] nvmet-fc: do not tack refs on tgtports from assoc
Date: Mon, 18 Dec 2023 16:31:00 +0100 [thread overview]
Message-ID: <20231218153105.12717-13-dwagner@suse.de> (raw)
In-Reply-To: <20231218153105.12717-1-dwagner@suse.de>
The association life time is tight to the life time of the target port.
That means we do not take extra a refcount when creating a association.
