Never mind, I see, the complaint is about the case where the id's don't
change, not about the directory case.  So Sachin's
0953e620de0538cbd081f1b45126f6098112a598 doesn't actually have anything
to do with this.

I'm fine with removing the id comparisons and changing the nfsd behavior
to match local filesystems.
