It's two function calls away from the use of i_lock, in a different file.
A quick grep on a warm, sunny Sunday afternoon between walking the
dog and heading down to the pub for a beer and dinner isn't going to
find that. :/

Anyway, this one looks fairly easy to fix as the code that locks
GlobalSMBSeslock is only called from this location. I'll code up a
patch to fix it.

Cheers,

Dave.
