Hey Guys, This commit seems to be needed to fixed up based on what the btrfs developers, are stating on their wiki. Other then the TODO list, which we can discuss here, is there any other parts of this patch that need to be rewritten, it's merged as of now but I can recreate new patches if needed from Linus's tree. The project idea is Clear unallocated space on the btrfs wiki. I AM NOT asking you to write the code just want to known is how you want this cleaned up. Cheers Nick
