In my 3.18.3 sources the file at Documentation/filesystems/btrfs.txt says:
"Btrfs is under heavy development, and is not suitable for
any uses other than benchmarking and review. The Btrfs disk format is
not yet finalized."
btrfs is no longer marked experimental in kernel and the file format is
stable. It is suited for general use except some features.
Maybe it's time to update btrfs.txt?
