It seems for me the similar problem can happen in __skb_trim_rcsum().
Also I doubt that that skb_checksum_start_offset(skb) checks in 
__skb_postpull_rcsum() and skb_csum_unnecessary() are correct,
becasue they do not guarantee that skb have correct CHECKSUM_PARTIAL.
Could somebody confirm it?

I've rechecked the code and I think now that other places are not affected,
i.e. skb_push_rcsum() only should be patched.

Thank you,
