BTRFS corruption w/kernel 3.13 while using docker -s btrfs

[Paul Harvey <csirac2@gmail.com>]

This is a "Damnit! I held the power button in and now it won't mount!" story, but I'm sharing what I found to learn what I can. And in case it's useful for btrfs development.

Also curious if my usage of Docker (an LXC thing, http://docker.io) has exacerbated things. I ask because it seems some btrfs mount options are breaking docker:
https://github.com/dotcloud/docker/issues/5429#issuecomment-42443919 - however, I'm not using space_cache or inode_cache myself.

Notes:
- I've taken a dd copy of the btrfs partition so that I can perform anything extra people would like to see.
- The following output is taken from the same machine, same partition layout but a fresh/working Debian testing install on a different disk. It should be reporting the same as it did before the corruption (it was definitely Linux 3.13).
- /dev/sda is a new disk, /dev/sdb3 is the corrupted btrfs partition.
- I have a single btrfs partition which contains the rootfs. I use subvolumes to separately snapshot /home, /vms, etc.
- mount options were: noatime,autodefrag,discard,compress=lzo

A timeline, starting around midday yesterday:
- I had some work to do and the VPN was slow, so on my laptop I upgraded docker from ~0.8.1 to 0.11.1.
- The upgrade stomped on my "-s btrfs" switch in /etc/default/docker which meant I was accidentally using docker with aufs for a while.
- I fixed this then purged all the containers and images (i.e. btrfs subvolumes).
- I did "docker pull debian:testing" which would have created a few new btrfs subvolumes.
- I ran some "docker build"s and at some point I had two builds going at once (two docker processes each creating btrfs subvolumes/snapshots at the same time).
- At some point one docker build was completed and the other was stalled trying to create a snapshot.
- Minutes later I noticed that my other applications were freezing up. The UI was still responsive and I could use the terminal.
- I looked at syslog and dmesg output in a terminal. There were no messages, ominous or otherwise coinciding with the disk i/o freezing up.
- I held in the power button.
- The reboot didn't boot. I ended up with the dreaded busybox shell, unable to mount btrfs rootfs...
- Removed disk and took a dd copy of sda3.

Other research...
Certain BTRFS mount options break docker -s btrfs:
- https://github.com/dotcloud/docker/issues/5429#issuecomment-42443919

The "AUFS on btrfs" thing has a few mentions in docker issues, perhaps it's nothing to do with btrfs though:
- https://github.com/dotcloud/docker/issues/829 - continued at...
- https://github.com/dotcloud/docker/issues/1075 - continued at...
- https://github.com/dotcloud/docker/issues/2961
- https://github.com/dotcloud/docker/issues/2056 # just another datapoint.
