I also think it fixes a serious problem with file locking on NFS. What I
dont think is that it has been extensively tested (I seen you stressed
file locking with it for a couple of days, but thats not enough).

I feel that it needs to get tested on different setups.

If Trond is confident it works reliably, I will apply it right away.
