I have worked on Tronds' patch for that. I posted my first attempt on the nfs list to see if Trond could sanity check it but he was clearly to busy. So I went ahead and did the best I could. This resulted in a port for 2.6 and 2.4 vanila kernel only. It is entirely untested and I expect will have problems as the depth of my understanding of the NFS subsystem is poor at best. I found trying to make it apply to a RedHat 2.4 kernel was something of a nightmare and have left it there for now.
