So, of the three boxes now running 2.6.37-rc2-git3, I have two mounted
with nordirplus.  One I booted with "nordirplus" has never logged the
error.  Another I haven't changed the fstab on, is still logging this
fairly often (nfsstat shows it has only made readdirplus calls):

[219158.456270] NFS: server 10.10.52.230 error: fileid changed
[219158.456273] fsid 0:4e: expected fileid 0x57bcf57c, got 0x57bd5442

Finally, on the last one I had remounted all of the NFS mount points with
that option, and there have been no errors since.
