Oh my... We can't simply release another v2.2.xx kernel with disfunctional NFS/KNFSD. Nobody in their right mind doing Linux<->Not-Linux NFS have any particular trust in Linux NFS any longer, and if we continue releasing broken NFS, people will shy away to *BSD or even commercial Unices. If I knew anything about NFS-programming, I'd help, but sadly enough, I don't, and I just haven't got the time right now to study the NFS spec's.
But I just don't see a v2.2.14 with non-working KNFSD as worth releasing, considering that fixed NFS/KNFSD was one of the major things that #14 would bring...
It bad enough that Linux NFSv2 write performance is so f**king bad, but if it's getting a read-performance of 4k, then... Bugger!
