Just fyi, NFSv4 avoids all of this by doing everything via NFS
over TCP to port 2049.

Unless someone stands up and thinks that it isn't an appropriate
change for 8.0, I'll email re@ at the end of to-day requesting the
merge of the one line change I already committed to head.
- It makes the default for Mount and the NFS Null RPC done before
   the mount(2) syscall use TCP by default. (It doesn't affect the
   behaviour when any of "udp", "tcp", "mntudp" options are
   specified.) Since Linux uses Mount over TCP for "tcp" mounts, I
   believe pretty well any server that supports NFS over TCP must
   also support Mount over TCP. (They'd get screamed at, otherwise.)

Thanks for the input, rick
