It's not clear to me how falling back to NFSv3 if v4 fails (and the
version wasn't explicitly set to v4) could ever cause a problem - it
might not help, but under what circumstances could it possibly be
harmful? I had a look at the linked thread from linux-nfs and no-one
there seemed to come up with anything concrete.
