Hannes Reinecke 751b2a7d62 [SCSI] dm mpath: propagate target errors immediately ... DM now has more information about the nature of the underlying storage failure. Path failure is avoided if a request failed due to a target error. Instead the target error is immediately passed up the stack. Discard requests that fail due to non-target errors may now be retried. Errors restricted to the path will be retried or returned if no paths are available, irregarding the no_path_retry setting.
