Subject: [RFC PATCH 0/3] differentiate between I/O errors

Refreshed Hannes' initial "scsi: Detailed I/O errors" patch against
v2.6.37-rc5.  v2 introduces __scsi_error_from_host_byte to avoid
the duplicate switch statement.  Also a few whitespace and comment
changes.

Split DM mpath change out to separate v2 patch; failed discard is now
retryable in the face of a non-target IO error.

Added improved block layer's I/O error message (based on the finer
grained I/O error returns afforded by SCSI).

Comments/suggestions are welcome.

Thanks,
Mike
