I've not seen an answer to my question in reply to the previous version
of this. Why would you do pretty printing of a variable that can just
return SUCCESS or FAILURE?
Is there anything prohibiting the scsi_eh_abort_handler provided by
the LLD from returning any of the other values like NEEDS_RETRY?
#define NEEDS_RETRY 0x2001
#define SUCCESS 0x2002
#define FAILED 0x2003
#define QUEUED 0x2004
#define SOFT_ERROR 0x2005
#define ADD_TO_MLQUEUE 0x2006
#define TIMEOUT_ERROR 0x2007
#define SCSI_RETURN_NOT_HANDLED 0x2008
#define FAST_IO_FAIL 0x2009
There is not, and hence I've added this patch.
Although the intention here would be that we should be
enforcing it, either by stating it in the description
of the function or programmatically.
Cheers,
Hannes
