You might want to list qgroups in order of some items, such as 'qgroupid',
'rfer'
and so on, you can use '--sort'. Now you can sort the qgroups by 'qgroupid',
'rfer','excl','max_rfer' and 'max_excl'.
For example:

The current show_qgroups() just shows a little information, and it is hard to
add some functions which the users need in the future, so i restructure it, make
it easy to add new functions.
In order to improve the scalability of show_qgroups(), i add some important
structures:

The patchset enhanced btrfs qgroup show command.
Firstly, we restructure show_qgroups, make it easy to add new features.
And then we add '-p' '-c', '-l',and '-e' options to print the parent
qgroup id, child qgroup id, max referenced size and max exclusive size
of qgroup respectively, add '-F' and

The error shown in your log seems to be a regression related to
subvolumes and a new uuid tree.

Not sure if it's anything interesting - I had the following entry in
dmesg a few days ago, on a server with 32 GB RAM. The system is still working
fine.

I'm still busy trying to figure out how to get VMs running without
corruption (see
http://www.spinics.net/lists/linux-btrfs/msg27300.html) and in the

Free btrfs_path structure before returning due to failure of calls to
btrfs_search_slot() or btrfs_next_leaf() functions.
