Btrfs devel - Nov 2013 - Btrfs-progs static compile failure due to multiple uuid-tree.o in linking paratemeters

Greetings

Btrfs-progs static compile fails due to multiple uuid-tree.o in
linking paratemeters:

build error:

I have no idea what I am doing but removing uuid-tree.o from objects
seems to help to compile btrfs-progs both as statically and
dynamically linked binaries:

diff --git a/Makefile b/Makefile

Yes, your fix is correct.

Are you going to send this fix as a git patch (git commit -s Makefile;
git format-patch -1; git send-email --to=linux-btrfs@vger.kernel.org
*.patch)?
