cifs.ko should be able to traverse a DFS link on the FS, after the DFS
mounted. My testing setup when I worked on this was the following:

//A/root
       |
       +- link -> //B/target
       +- sublink -> //B/target/sub

//B/target
       |
       + sub/
          |
          + dir/
              |
              + files..

And I had a script
- mounting //A/root and running cd&ls in /, /link, /link/sub,
  /link/sub/dir, /sublink, /sublink/dir
- mounting //A/root/link and running cd&ls in /, /sub, /sub/dir
- mounting //A/root/link/sub and running cd&ls in /, /dir
- mounting //A/root/sublink and running cd&ls in /, /dir
- mounting //A/root/sublink/dir and running cd&ls in /

And all worked for vers={1.0,3.0}, A being {samba, Windows Server 2016},
B being {samba, Windows Server 2012 R2} when I submitted the patches.
