After that nothing happens and cifs-utils throws "Invalid argument". I dont know what argument should be wrong. I also tried cifs-utils 6.7 from the git repo with no luck.

I've just tested again kernel master against WS2016 with a link to a
WS2012 server and I can:

* mount to namespace and cd in the link
* mount the link
* mount a subdir under the link

and everything works properly with vers=2.0 vers=2.1 vers=3.0. With
vers=3.11 windows doesn't let me do the initial tree connect for some
reason.

mount -t cifs -vvv '//ws2016.suse.de/dfs3/link/sub' /mnt -o \
  'vers=3.0,domain=xyz,username=administrator,password=xyz'

Have you made sure your system can resolve both the main server hostname
and the target server (the hostname in the DFS query response)? Are you
using vers=xyz option when mounting?
