Description of problem: The json output of the io-stats debug xlator quotes the numbers as strings instead of just printing them as numbers. This makes parsing them in a strongly typed language more difficult than it should be. This is an easy fix so I'll be following up with a patch to correct the output.
Version-Release number of selected component (if applicable):
As far as I know it's been like this since first released. Commit: d3e496cbcd35b9d9b840e328ae109c44f59083ce and bug id: 1271310
How reproducible: Easily reproducible by enabling the iostats fop diagnostics.
