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.

I did test the Hannes original patch with the latest Linus' git tree! I
used scsi_debug to simulate path failures as well as 'Media' failures
and it did work as expected. I will test your patches soon.

Hi Malahal,

I was wondering if you had any feedback (testing or otherwise) for these
patches:

https://patchwork.kernel.org/patch/384612/
https://patchwork.kernel.org/patch/384602/
https://patchwork.kernel.org/patch/390882/

We haven't heard from Hannes in a bit but I was hoping we could at least
understand that the few changes I made are agreeable and working as
expected.

Thanks,
Mike
