OK, great.

$ git log --pretty=oneline v2.6.18..origin fs/nfs fs/nfsd net/sunrpc | wc -l

So a lot of patches have touched the nfs client and server code since
2.6.18.  It would be a non-trivial project to sort out which of those
affect NFSv4 specifically and which are important, and then backport
each of them to 2.6.18.

Upgrading the whole kernel at once, when at all possible, is a lot
easier.
