Subject: [PATCH 05/13] aacraid: use scsi_host_complete_all_commands() to terminate outstanding commands
Date: Wed, 4 Dec 2019 15:59:10 +0100 [thread overview]
Message-ID: <20191204145918.143134-6-hare@suse.de> (raw)
In-Reply-To: <20191204145918.143134-1-hare@suse.de>
Use scsi_host_complete_all_commands() to terminate all outstanding commands
instead, and change the command result for terminated commands to
the more common 'DID_RESET' instead of 'QUEUE_FULL'.
