The fundamental on-disk structures for btrfs and ext4 are totally different. You will get very confused if you expect the ext4 code to work in the btrfs module, or even if you expect structures to be similar. But first -- answer my questions in the reply I made to your patch just now. Do nothing else until you can answer all three of those questions sensibly.
