New Revision: 260109
URL: http://svnweb.freebsd.org/changeset/base/260109

Log:
  MFC: r259771
  The NFSv4.1 client didn't return NFSv4.1 specific error codes
  for the Getattr and Recall callbacks. This patch fixes it.
  Since the NFSv4.1 specific error codes would only happen for
  abnormal circumstances, this patch has little effect, in practice.
