I am testing this with current OverlayFS (here: as module).

# grep LOCKDEP /boot/config-3.15.0-rc7-58.1-iniza-small
CONFIG_LOCKDEP_SUPPORT=y

( My full kernel-config is attached. )

Attached is one patch to fix a hardcoded path to mount binary.

I cannot run the testsuite successfully...

Not sure what's wrong.
