As part of the attempt to go upstream, this "hubcap" guy you see
in the comments worked on a thing that changes 64bit userspace handles
back and forth into 128bit kernel handles... we did this because
one day, when we have orangefs3, we will be using 128bit uuid-derived
handles, and we believe it is our responsibility to not break the
upstream kernel module.
Anywho, I bet you are right Al, he messed up this part of it...
I'll look and see if that is really so, and get it fixed.
