--- Comment #22 from Willem de Bruijn (willemb@google.com) ---
The following fix has been merged

  skbuff: orphan frags before zerocopy clone
  268b790679422a89e9ab0685d9f291edae780c98
  v4.15-rc5~10^2^2~1
  http://patchwork.ozlabs.org/patch/851715/

That resolved another report of what is most likely
the same issue. Tested together with this follow-up
that is currently awaiting review to net-next 

  skbuff: in skb_segment, call zerocopy functions once per nskb
