The patch looks to be backported (per BZ comment). Meaning: It's already 
upstream. The latest stable kernel (2.6.37) seems to have the patch[1] 
albeit the code is vastly different.

Have you tried setting "async" on the NFS server shares? I have had to 
do that on my systems. Everything gets bogged down in large gigabyte 
transfers if I don't.
