[ Re-Tested with 3.15.0-rc8-1-iniza-lockdep ]

Running the impermissible test on OverlayFS with TERMSLASH=1 is
successful here (TERMSLASH=0 still fails):

# LC_ALL=C TEST_OVERLAYFS=1 TERMSLASH=1 ./run.sh

[ NOTE-1: I still see the reported call-trace which you Dave see as a
problem in OverlayFS. ]
[ NOTE-2: The call-trace I have seen once (TERMSLASH=0). ]

[ ^^ Miklos any idea? ]

Diverse logs, kernel-config and dmesg files attached.

Hope this feedback helps you.
