I download the files:
git clone http://git.darksatanic.net/repo/btrfs-progs-unstable.git/
integration-20110630

Then I tried to apply the patch you mentioned:
patch < rem.diff
but it's failing:
The rem.diff is the file attached

Here is the error I am getting:
patching file mkfs.c
Hunk #1 FAILED at 1060.
Hunk #2 FAILED at 1070.
2 out of 2 hunks FAILED -- saving rejects to file mkfs.c.rej
patching file volumes.c
Hunk #1 FAILED at 868.
Hunk #2 FAILED at 920.
2 out of 2 hunks FAILED -- saving rejects to file volumes.c.rej
I think the file I created is wrong.
What is the accepted format for the patch command?
