Should be no problem. If Vinod wants to pick it up:
Acked-by: Arnd Bergmann <arnd-r2nGTMty4D4@public.gmane.org>
Note that you can configure git send-email to automatically drop
Cc's to stable-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, and that the correct address
is the one with vger in it, not just stable-DgEjT+Ai2yi4UlQgPVntAg@public.gmane.org
