Yes, you cannot cross a MOUNTPOINT boundary with reflink.
Or, for that matter, btrfs subvolume snapshot.

I get "Failed to clone: Invalid cross-device link". Is it expected?
Basically this is (on openSUSE TW which has root on subvolume)
mount -o subvol=/ /dev/vda1 /mnt
btrfs sub create /mnt/var/cache
cp -a --reflink=always /var/cache/* /mnt/var/cache

dunno if this thread is dead, but im inclined to patch in cp --reflink
to "fdupes" prog. It currently does provide a poor-man's dedupe via
md5sum and hardlink, or delete.
all the better if the distro-kernels can backport cross-snapshot
reflinks sooner than later.
