Subject: [PATCH v2 03/28] scsi: iscsi: Drop suspend calls from ep_disconnect
Date: Tue, 25 May 2021 13:17:56 -0500 [thread overview]
Message-ID: <20210525181821.7617-4-michael.christie@oracle.com> (raw)
In-Reply-To: <20210525181821.7617-1-michael.christie@oracle.com>
libiscsi will now suspend the send/tx queue for the drivers so we can drop
it from the drivers ep_disconnect.
Reviewed-by: Lee Duncan <lduncan@suse.com>
