Subject: [PATCH v2 15/28] scsi: iscsi: Fix completion check during abort races
Date: Tue, 25 May 2021 13:18:08 -0500	[thread overview]
Message-ID: <20210525181821.7617-16-michael.christie@oracle.com> (raw)
In-Reply-To: <20210525181821.7617-1-michael.christie@oracle.com>

We have a ref to the task being aborted, so SCp.ptr will never be NULL. We
need to use iscsi_task_is_completed to check for the completed state.
