There was also a patch submitted by Li Zefan for LZO support in btrfs-progs:

http://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg06931.html

If I recall correctly, btrfs-progs will throw out an error once you
use LZO compression since btrfs-progs needs to be made aware of the
INCOMPAT flag in the patch submitted above.

My local btrfs-progs git repository also incorporates patches to
support mixed data+metadata (which also uses an INCOMPAT flag aleady
in the kernel code) and for the filesystem diskinfo command.

A quick search for "btrfs-progs" in my Mailing List archive turns up a
number of other btrfs-progs patch proposals since October.
