Hi all,

I duplicated patches in this series :(
My bad, I was mistaken in 'git format-patch'.

Can you consider only the "[PATCH v3 RESEND n/6]: xxxxxx" in this review.
The other patches ("RESEND PATCH v3") are the duplicated ones.

If ok I will send a clean v4 series.
Of course, if some modification are needed, I will also send a clean v4.

Let me know if a clean v4 is needed right now.

Sorry for this mistake.
Regards,
Hervé
