Steve,

	I now have a 2.6 built kernel so I'm doing some cifsfs
tests - I'd recommend trying tridge's ping_pong.c test for the
byte range locking code - find it at :

http://samba.org/ftp/unpacked/junkcode/

under the ping_pong.c link.

I'm going to be working with this to ensure everything works
well with Samba 3.x.

Jeremy.
