Hi Steve,

I'd like to track down the NFS locking problems you've reported, and wondered
if you could send a copy of the script you're using for testing, or any other
simple example to illustrate the problem.

I don't use NFS locking for everyday work, but have tested it in the past
with seeming success, so my assumption is that some recent change has caused
(or simply revealed) the problem.

Any idea which kernel release first showed the locking problems?

Regards,
Bill
