Chaitanya is already working on enhancing tracing. I seem to recall
blktrace being fairly flexible with what it digests.

On top of that, we also have the option of changing the error path
output as opposed to changing the tracing ditto should that be an issue.

My main point is that there is probably going to be close to a 1:1
mapping between what you would want to see in an error message and what
you would want to see in tracing. So it would be good to use the same
plumbing for both.
