[dm-devel] Re: [RFC PATCH 1/4] convert block layer drivers to blkerr error values

[Jeff Garzik <jgarzik pobox com>]

In general, I'm a bit worried about these changes, for two overall reasons:

1) I didn't see any analysis of the ultimate end users of block layer 
error values:  the filesystems.

2) This begins to converge with the SCSI layer's error/retry/etc. error 
values.  Since I would eventually like to see SCSI's non-SCSI-related 
infrastructure "moved up", a bit -more- alignment with SCSI at this 
stage might be nice.
