The changes to knfsd are fairly big and mean that every filesystem
type that is to be exported needs to explicitly provide support for
knfsd.

I have almost completed doing this for
  ext2fs reiserfs isofs ufs efs

which were the only ones that were mentioned when I asked "what
filesystem types do you want to export" on the nfs list.
The isofs stuff needs more work to be *right*, but it should be at
least as good as the current code provides. (i.e. it works as long as
things don't get flushed out of the dentry cache).

The reiserfs bit needs work to get generation number checking done.
This is being worked on by  Danilov Nikita.

I hope to put out a patch set for testing in a day or so and possibly
suggest it to Alan for his -ac series.  I don't see it going into
2.4.2, but 2.4.3 might be possible if Linus agrees.
