Josef Bacik 56f762659a btrfs: do not allow non subvolume root targets for snapshot ... commit a8892fd719 upstream. Our btrfs subvolume snapshot <source> <destination> utility enforces that <source> is the root of the subvolume, however this isn't enforced in the kernel. Update the kernel to also enforce this limitation to avoid problems with other users of this ioctl that don't have the appropriate checks in place.
