  It was btrfs-convert (I could have told that in my original email as well
but it didn't seem important) - i.e. inplace convertor from ext4 to btrfs.
So it really needed to get the file type from the directory block to fill
in appropriate btrfs structures.

  btrfs-convert is part of btrfsprogs so feel free to have a look. I don't
think we can actually provide some high level functionality to serve its
needs. It really just needs to do readdir(2) on fs image which is what is
already implemented in libext2fs.
