Petersen" Cc: Christoph Hellwig , James Bottomley , linux-scsi@vger.kernel.org, Hannes Reinecke Subject: [PATCH 03/13] dpt_i2o: use scsi_host_complete_all_commands() to abort outstanding commands Date: Thu, 13 Feb 2020 15:04:12 +0100 Message-Id: <20200213140422.128382-4-hare@suse.de> X-Mailer: git-send-email 2.16.4 In-Reply-To: <20200213140422.128382-1-hare@suse.de> References: <20200213140422.128382-1-hare@suse.de> Sender: linux-scsi-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-scsi@vger.kernel.org Rather than traversing all outstanding commands manually use the scsi_host_complete_all_commands() helper to terminate all commands during reset. With that we can drop the cmd_list usage from the midlayer.
