When CH sent v4 to the list it was corrupted, v3 is the one to reference for content.

I see your other email you resolved the conflicts - so please let me know if you want to proceed with dropping CH's series or not, I'll make a special effort to get that change into tomorrows linux-next if you want (it is already 6pm here) Regards, Jason
