Is doing mount -u -o udp useful for you on an NFS mount?

[Rick Macklem]

Hi,

Using a "mount -u" to change from TCP to UDP for an
NFS mount is somewhat broken for both NFS clients.
To make it work correctly is not trivial.

As such, I'd like to find out if anyone needs this
capability? (Note, I am not talking about UDP mounts
in general, just the case of switching a TCP mount to
a UDP mount without doing an unmount/mount.)

Thanks in advance for your feedback, rick
