I have implemented the above function, but they haven't gone into upstream
Btrfs-progs.

You can try this:

	http://github.com/miaoxie/btrfs-progs.git qgroup

Maybe i need rebase the patch-set later, But you can try it firstly, if you want to see
every qgroup's parent, you can add option '-p':

btrfs qgroup show  -p <mnt>


If you want to see what is assigned to 1/1, you can use:

btrfs group show -c <mnt>

Further, if you want to see a specified path's parent qgroup, you can use it:

btrfs group show -F/-f <path>

Also '-l' and '-e' print limit size of qgroup.

Thanks,
Wang
