This part is definitely my fault.  I've gone through a bunch of
variations on bigger and smaller tools, and had to juggle the kernel
maintenance as well.

Aside from making sure the kernel code is stable, btrfsck is all I'm
working on right now.  I do expect a release in the next two weeks that
can recover your data (and many others).
