Basically, phoronix showed there is a --repair option. After enabling
snapshotting and playing around with the various discussed options, I
discovered that --repair and no special mount options was sufficient
to get the files removable.

I'm curious, whether running it directly on newer kernel (e.g. latest
ubuntu kernel-ppa/mainline) will be able to "solve" the problem, even
without btrfsck.

Also note that if by "snapshotting" you mean "create LVM snapshots",
then you might be in for another surprise, as btrfs doesn't play nice
with block devices with the same fs UUID. Don't rely on that as backup
option.

Now what I'm hoping for is better documentation on btrfsck even if it
just boils down to a brief enumeration of the options as that would be
better than nothing which is what we have now. Do I need to file a bug
or is this sufficient?
