On the other hand, "df" reports global figures, whereas "du" reports values for a file or set of files. "btrfs fi df" also reports (one set of) global figures, and a hypothetical "btrfs fi du" (which will probably surface once Arne finishes the qgroups stuff) will report on subvolumes and/or sets of files.
