Your patch fixes the buildstats issue for building on a btrfs volume as well. bitbake no longer hits the exception and diskstats are omitted. Theoretically, this information would be available for btrfs, but it is not discoverable in the way buildstats currently collects the disk statistics. However, this is a seaprate issue, I think.
