This is exactly what we'd like to get clarified in this very special case.
Since Thomas didn't put a Co-developed-by in the first place, I prefer to
respecting his choice i.e.:
From: Jing Liu <jing2.liu@xxxxxxxxx>
Signed-off-by: Jing Liu <jing2.liu@xxxxxxxxx>
Signed-off-by: Yang Zhong <yang.zhong@xxxxxxxxx>
Signed-off-by: Thomas Gleixner <tglx@xxxxxxxxxxxxx>
Signed-off-by: Jing Liu <jing2.liu@xxxxxxxxx>
Signed-off-by: Yang Zhong <yang.zhong@xxxxxxxxx>
Following this rule then the SoB order in all other patches also need
be fixed, e.g. both Jing's name and Yang's name will occur twice
to reflect the chronological order in most patches. But I'm not sure
what's the best way to handle it since Paolo already puts the entire
series in his tip.
Can this series gets an exempt given all participated names already
have their SoB in this special case?
If must be fixed we can certainly provide updated SoB history for
every patch. The burden might be on Paolo's side and if it does happen
I really want to say sorry here for not getting this open clarified earlier...
Thanks
Kevin
