I have a DTrace patch for the new NFS client. The current version,
(which would apply to a -current kernel recently but if it won't
 patch now, I can easily fix it) is at:
  http://people.freebsd.org/~rmacklem/dtrace.patch

I have been waiting for a review/test of it, but if you could test
it, that would be greatly appreciated. Once built, the module is
called dtnfscl.

Alternately, if you could email me some simple instructions on how
to test it, that would be appreciated as well. (I have never used
DTrace, so I have no idea how to test it.) It is basically a clone
of the other one, except for the NFSv4 stuff, so it "should" work
about the same.

If I don't get any review/testing done, I'll commit it "as is"
before the code slush deadline.

ps: I'll try applying the patch now and fix it if it needs changing,
    so if you download it from the above in a few hours, it should
    be ok.
