    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

    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.


    Hannes Reinecke (1):
    scsi: Detailed I/O errors

    Mike Snitzer (2):
    dm mpath: propagate target I/O errors immediately
    block: improve detail in I/O error messages
