I don't know anything about copy_from_user, but if it is a memory copy
function then what is happening is that you are copying your first struct,
including a _pointer_ to your second struct, not the second struct itself.
Not only do you need to copy the second struct, but you also need to
update the first struct to point to the new copy of the second struct.
This might be a good time to write a function or macro to handle
duplicating your struct invisibly.
