Originally I had said:

   > Signed-off-by: Tushar Sugandhi <tusharsu@...ux.microsoft.com>
   > Signed-off-by: steven chen <chenste@...ux.microsoft.com>

   Before the "Co-developed-by" tag was defined, it was implied simply by this ordering
   of the "Signed-off-by" tags.
   
   For those patches you didn't modify, simply import Tushar's patch with him as the
   author and add your Signed-off-by tag after his.

Thanks, James, for the explanation of using "From: original author <email>" to force the
author to be Tushar.
