I mentioned this somewhat informally to Chris Mason last week. I
provided him the message, and he said:
Well, the block reservation code in btrfs is even more complex than
xfs. Usually it means we didn't properly free the things we reserved.
If you send along which version of btrfs you were using we can try to
track it down.I (finally) just did that--I sent him the log messages from above.
