If you're just wanting info about one subvolume, just use 'subvol show'. 
  As far as 'subvol list', that was mentioned in discussion on github of 
future changes for btrfs-progs (although I don't think that's gone 
anywhere).

Checking if something is a snapshot is easy though, do 'btrfs subvolume 
show -qt', if the Parent UUID column is a -, it's a regular subvolume, 
if not, it was created as a snapshot.
