Subject: [PATCH 27/31] libsas: add tag to struct sas_task
Date: Mon, 22 Feb 2021 14:24:01 +0100 [thread overview]
Message-ID: <20210222132405.91369-28-hare@suse.de> (raw)
In-Reply-To: <20210222132405.91369-1-hare@suse.de>
All block layer commands now have a tag, so we should be storing
it in the sas_task structure for easier lookup.
