I'm a bit confused about the `get/update_volume_notes` subs.
You said they are deprecated and unused. However, the DirPlugin does
call it when `$attribute eq "notes"` in `get/update_volume_attribute`.

Since BTRFSPlugin uses Plugin as a base and not DirPlugin and we pass
$class (== BTRFSPlugin) to it, setting notes should not work with this patch?
