From d3d328919f278eda489a482541583f79987ad0e2 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Fri, 19 Feb 2016 09:17:16 +0100 Subject: scsi_dh: add 'rescan' callback If a device needs to be rescanned the device_handler might need to be rechecked, too. So add a 'rescan' callback to the device handler and call it upon scsi_rescan_device(). The rescan callback will be invoked from the Unit Attention handling of ASC/ASCQ 3F 03 (INQUIRY DATA HAS CHANGED).
