So this means that "the author must be the first SoB" is not an absolute 
rule.  In the case of this patch we had:

From: Jing Liu <jing2.liu@xxxxxxxxx>
...
Signed-off-by: Thomas Gleixner <tglx@xxxxxxxxxxxxx>
Signed-off-by: Jing Liu <jing2.liu@xxxxxxxxx>
Signed-off-by: Yang Zhong <yang.zhong@xxxxxxxxx>


and the possibilities could be:

1) have two SoB lines for Jing (before and after Thomas)

2) add a Co-developed-by for Thomas as the first line

3) do exactly what the gang did ("remain practical and do only an SOB 
chain")
