Hi all,

While writing my own NFS client, I have found a simple test case that
triggers a general protection fault on the NFS server.

The NFS 4 compound is: PUT_FH, READ, READ
The second read causes the fault.

More information, including how to reproduce the bug is available in
the bug tracker: https://bugzilla.linux-nfs.org/show_bug.cgi?id=402

Thank You,
-Jan

Applied and pushed out.  (But not actually tested!  Let me know if
there's a problem.)
