Hi Tang Bin,

A quick query on this sign off sequence as I'd like to check what the
intended meaning is.

If you both developed this patch, please use the Co-developed-by: tag
to indicate that.   If Zhang Shengju wrote the patch then you sent it
upstream, please fix the 'from' field on the email to reflect that.

Patch itself is good.

Thanks,

Jonathan
