On Fujitsu ETERNUS systems, sense code ABORTED COMMAND with ASC/Q C1/01 is used to indicate temporary condition where the storage-internal path to a target is switched from one controller to another. SCSI commands that return with this error code must be retried unconditionally (i.e. without the "maybe_retry" logic in scsi_decide_disposition); otherwise dm-multipath might initiate a failover from a healthy path e.g. for REQ_FAILFAST_DEV commands. Introduce a new blist flag for this case. [mkp: applied by hand] Signed-off-by: Martin Wilck <mwilck@suse.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
