The problem is that the reference target isn't called "up_rcu" in the file

Certainly "up_rcu" seems like a better name. I do believe, though, that
you can also use the title directly:

And the problem is the same, it's list_rcu_doc in the actual source file.
Jiang, as with so many things in software, if you haven't tested it, it
probably doesn't work. Please actually run "make htmldocs" and look at
the results to be sure that they are what you expect. (Along those lines,
it would also be good to add the new directory to Documentation/index.rst
so that it gets built with the rest).
