Can you pull my btrfs-progs git tree here

git://github.com/josefbacik/btrfs-progs.git

build it and run ./btrfs-image -w -c9 -t4 /dev/whatever blah.img

and upload blah.img somewhere that I can pull this down.  Also please open a bug
on kernel.bugzilla.org (make sure to set the component to Btrfs) so I can track
this issue.  Thanks,

Josef
