In btrfs, there is a bug about btrfs' truncate codes, it'll leak
some fs space as the truncate operation proceeds. If this truncate

patch fot btrfs to fix this issue.

This version looks good to me. Just one more thing to confirm with you,
did you verify that test passed with your btrfs patch applied?
Yes, with my fixing patch, this case will pass for btrfs.
