I was playing with docker and then I found with btrfs list many docker subvolumes like this one:
ID 23305 gen 3405505 top level 22147 path var/lib/docker/btrfs/subvolumes/1464e922.....
I do not use docker. How to get rid off of these subvolumes? There is too many to just delete it one by one... Thanks

to prevent this from happening. That's the driver that Docker will (usually) use if/var/lib/docker
is not on a btrfs filesystem.
