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.
