Hey Chuck,

Thanks for the (very) fast reply! :-)

Indeed, that's also a good outcome. Personally I've never seen these 
legitimately fire in production outside of cases like the one described, and we 
historically ran a pretty diverse set of use cases for NFS.

Maybe safer to convert to a tracepoint just in case? Either way sounds fine 
though -- let me know what you'd like for v2 and I'll send it over. :-)

Thanks!

Chris
