    kernel - Do not invalidate the vnode+children in the NFS core on ESTALE
    
    * When NFS encounters ESTALE it would try to invalidate the related
      namecache topology in the core socket code, requiring an exclusive
      lock on related namecache entries.  This is not compatible with
      shared namecache locking because it can occur as part of any operation,
      even simple GETATTRs.
    
    * Remove the invalidation for now.  The kernel already has a high-level
      solution in place for terminal nodes but we will also need one for
      traversals.
