I tried it.

I still have direct modification of rr2 and not the copy to rr4,
so if I would aim for binary equalness it is still not the same,
but it seems that it can't be done another way.
OK - it is not temporarily copied to rr4, but
directly modfied in
rr2 and then assigned to u.u_dirp. It should be "the same" - But
- ln(1) does not work with this code. Instead of creating a
hardlink, it creates a new empty file (different inode).
Are you sure this is where the problem is?
