Hi Neil,

I think if you could add the commit author in the cc list will be better.

Because this could let him know about his code's issue and he is the
always the best person to review the patch.

Thanks,
Michael

The commit author is me, and its recorded by the Signed-off line, as well as the
Authorship tag in git.  Not really sure what you're driving at here.

Yes, Git already does that, as noted above.

Sorry, What I mean "commit author" is who mentioned in you commit log,
for this case should be this guy: alan.carew@intel.com I think.
Sorry for I did not say it clearly.

Yourself, of course, should be in the list.

Thanks,
Michael
