--- Comment #1 from Lennart Poettering <lennart at poettering.net> ---
I am pretty sure we should issue the ioctl always, regardless what the backing
fs is. Maybe one day the ioctls for snapshotting become generically used...

We can certainly improve the log message though, and tell the use that he needs
btrfs as source if we encounter ENOTTY here...
