Subject: [PATCH 2/7] dpt_i2o: return SCSI_MLQUEUE_HOST_BUSY when in reset
Date: Mon, 10 Jun 2013 13:11:48 +0200 [thread overview]
Message-ID: <1370862713-41323-3-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1370862713-41323-1-git-send-email-hare@suse.de>
When the HBA is in reset we should be returning 'busy' and not
rely on the obscure 'last_reset' feature.
