Subject: snapshot strange behaviour

Hello,
During doing backups I found strange behaviour... 2.6.37, latest btrfs-
progs from git
nbgentoo ~ # btrfs subv crea a
Create subvolume './a'
nbgentoo ~ # cd a
nbgentoo a # btrfs subv crea b
Create subvolume './b'
nbgentoo a # touch b/file
nbgentoo a # ls -l b/
total 0
-rw-r--r-- 1 root root 0 Jan 23 08:14 file
nbgentoo a # cd ..
nbgentoo ~ # btrfs subv snap a x
Create a snapshot of 'a' in './x'
nbgentoo ~ # ls -l x/b/
total 0
and also
nbgentoo ~ # cd x/
nbgentoo x # btrfs subv dele b
ERROR: 'b' is not a subvolume
Is this a bug or intended behaviour and I am missing something something?
How to snapshot a subvolume, containing another subvolumes?
(I create subvolume backup, under this another subvolumes as not always I
want to snapshot the whole backup subvolume).
Thank you
Lubos
