   Cc: stable@vger.kernel.org
 
+Use ``Cc: stable@kernel.org`` instead when fixing unpublished vulnerabilities:
+it reduces the chance of accidentally exposing the fix to the public by way of
+'git send-email', as mails sent to that address are not delivered anywhere.

 Once the patch is mainlined it will be applied to the stable tree without
