Create a large filesystem, mount it using -o inode64 on a 32-bit kernel,
find an inode that actually uses more than 32-bits, and try to access
it from an nfs client.

Alternatively you could probably reproduce it using the open by handle
system calls, I have an idea how to turn that into a test case for
xfstests using a large loopback filesystem.
