Since CoW / reflink does not seem to work between subvolumes (a bug or a
feature?), is it somehow possible to get the subvolume (used) size?
There is a standard df tool, but it can be a lengthy process for
filesystems with lots of files.
"btrfs filesystem df" only shows total size for the whole btrfs filesystem.
Say, I create subvolumes called public, office, staff and pack a lot of
files there. Does btrfs somehow allows to get the current size of these
subvolumes (other than using df tool to traverse all files and directories)?
