 Looks good to me.

 By the way, one thing I noticed when I tested the new NFS
 implementation (mainly for the version 3) was that NFS file handle
 seemed not compatible with the old one.  The reason why I thought so
 was that when I went back and forth between the two implementations
 on an file server, I had to do remount on all of the clients due to
 "Stale NFS file handle" error.

 I am sorry for my laziness not investigating the changes, but is my
 understanding correct?  If true, this will be an obstacle when one
 wants to seamlessly upgrade his NFS server with a lot of clients.  I
 want to know if there is any workaround for that.
