Hello,
I sent this patch a few weeks ago and got no reply (and nothing showed
up on https://patchwork.kernel.org/patch/9302825/). Could you please
consider it for 4.9?

Thanks,
Nicolas

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
