  SVN rev 216700 on 2010-12-25 21:56:25Z by rmacklem
  
  Modify the experimental NFS server so that it uses LK_SHARED
  for RPC operations when it can. Since VFS_FHTOVP() currently
  always gets an exclusively locked vnode and is usually called
  at the beginning of each RPC, the RPCs for a given vnode will
  still be serialized. As such, passing a lock type argument to
  VFS_FHTOVP() would be preferable to doing the vn_lock() with
  LK_DOWNGRADE after the VFS_FHTOVP() call.
