I don't think so, the problem is kernel and btrfs-progs all need to
modify extent buffer, which make the read time conversion become a
burden in write path.

That's strange, the branch is originally based on an older master, as
you can find in the github.

I guess there are some more btrfs related code change since then, I'll
rebase them to latest master, and update the github repo then.
