From abbca103a02ff0e87569c38be518f9cb2d6baabc Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Mon, 14 Aug 2006 18:51:00 +0200 Subject: ieee1394: sbp2: better handling of transport errors If the target signals a transport failure via status block, complete the request with DID_BUSY to indicate to the SCSI subsystem that the command may succeed when retried. Also log diagnostic information if the status block shows a transport related problem. It may point to hardware faults.
