Hi,
I pulled in v17 (current) into Linux-Next (next-20130313) and built
OverlayFS as a module.
Unfortunately, I do not see any success message on loading it.

Highly appreciated to see such a message!
Test-case script attached (needs an additional patch on top of
overlayfs.current, see attachments).
