NFS locking and linux NFS server

[Christoph Egger]

Hi all!

  I have a Linux Host (2.6.32 kernel, Debian stable) providong NFS
shares. Locking files on that share works fine for linux clients [0]
while it fails on a freebsd 9.0-STABLE system. The interwebs indicate
there have been problems witha buggy linux implementation back in 2006
but no more hits for that problem in recent times so I assume it's
fixed?

root at freebsd /mnt/
11:27 0 # kldstat -v | grep nfs
		341 nfscommon
		386 nfslockd
		344 nfsd
		385 nfssvc
		342 nfs
		343 nfscl
		384 nfslock
                                                                                                                                                                                                                                                                                                                          
root at freebsd /mnt/
11:28 0 # flock test -c ls
flock: test: Operation not supported

root at freebsd /mnt/
11:31 0 # mount | grep nfs
10.70.255.8:/home/ on /mnt/ (nfs)

Regards

    Christoph
