I assume you mean the first instance of io-stats that recognizes its
own name in the argument, or else the setattr might still get turned
around before it gets to where it's intended to take effect.  Another
option would be to put the desired io-stats level in the xattr name
instead of its value.  I'd use levels instead of names because names
are made up internally and not readily/safely guessable by the user.
This would require that we pattern-match on the xattr name instead
of doing a direct string comparison, but that seems easy enough.
