Eryu,

Actually, I needed to make a change to overlay/069, so please hold on
with these.

For test coverage, the interesting cases for nested overlay are:
- lower overlay is samefs
- lower overlay is non-samefs

That last case is especially interesting to exercise xino bit overflow,
because lower overlay uses the high ino bits.

This is not how I implemented overlay/069, so I made this change and
it caught another bug in upstream.

I have more nested tests coming soon, so I will post those along
with v2 of these tests.

Thanks and sorry for the noise,
Amir.
