Can you explain roughly how this is intended to work, or point me at a
document explaining it?

I'm trying to figure out how the file lock checkpoint will work with
cluster filesystems, or if there needs to be a mechanism to turn this
feature off for those filesystems. What prevents the lock state changing
in an incompatible way between the checkpoint and the restore?

Steve.
