Subject: [PATCH v2 28/28] scsi: qedi: Wake up if cmd_cleanup_req is set
Date: Tue, 25 May 2021 13:18:21 -0500 [thread overview]
Message-ID: <20210525181821.7617-29-michael.christie@oracle.com> (raw)
In-Reply-To: <20210525181821.7617-1-michael.christie@oracle.com>
If we got a response then we should always wake up the conn. For both
the cmd_cleanup_req == 0 or cmd_cleanup_req > 0, we shouldn't dig into
iscsi_itt_to_task because we don't know what the upper layers are doing.
We can also remove the qedi_clear_task_idx call here because once we
signal success libiscsi will loop over the affected commands and end
up calling the cleanup_task callout which will release it.
