   Don't do that. It's pretty old, and there's been a large number of
fixes in btrfs since then. I would recommend using the very latest
kernel you can -- preferably an -rc series kernel (after -rc3
or so, though), or the latest release kernel.

   The only real reason to upgrade your btrfs tools is to get access
to the newer features of the FS.

   You'll have to ask the backports people about that. The btrfs
developers don't have any control over what ends up in most
distributions.

   You should definitely be on 3.1 or 3.2 kernel at the moment.

   In that case, I'd suggest either building from the git source tree
for tools (see the wiki[1] for instructions), or, if you insist on
having .deb packages, doing your own backport:

$ apt-get build-dep btrfs-tools
$ apt-get source -t unstable btrfs-tools
$ cd btrfs-tools-0.19+20111105
$ fakeroot debian/rules
$ sudo dpkg -i ../btrfs-tools-0.19+20111105.deb   # This may be a different name

   Hugo.
