I see "Changes requested" on Patchwork. Which ones?

1/8 regarding gro_node? Nobody proposed a solution which would be as
efficient, but avoid using struct_group(), I don't see such as well.
I explain in the commitmsgs and cover letter everything. Jakub gave me
Acked-by on struct_group() in the v3 thread.

Thanks,
