Thanks for the reply, but for some reason btrfs-fins-root does not work
on this file system. Here is what I get:

[jdg@tiare tmp]$ btrfs-find-root x220_home.img -o 5
Super think's the tree root is at 115230801920, chunk root 131072
Went past the fs size, exiting[jdg@tiare tmp]$

I can mount the file system, access the files, though obviously not the
deleted directory.
