How do I find the root filesystem of a subvolume?
Example:
root@fex:~# df -T
Filesystem Type 1K-blocks Used Available Use% Mounted on
- - 1073740800 104244552 967773976 10% /local/.backup/home
root@fex:~# btrfs subvolume show /local/.backup/home
/local/.backup/home

I know, the root filesystem is /local, but who can I show it by command?
