That is understandable. NFS could certainly be worth testing.

The patches for smbfs are (finally) available at:
	http://www.hojdpunkten.ac.se/054/samba/index.html

You want the smbfs-2.4.17-2.5.patch.gz patch and apply that to a 2.4.17
kernel.

The features include:
	Large File Support (>2G files)
	Unicode Support
	Support for fcntl locking and oplocks

The first 2 require changes to smbmount to become "active". But for
testing the locking you don't need to make any changes to smbmount.


Sorry for the delay in responding with the link. I found some problems
with the code the locking code depends on, and it seemed pointless giving
you a patch that I knew would crash your machine.

The locking code has a few known problems still, so don't expect it to 
work (it may, but assume that it will fail :)
