From cb002d074dabfaa2248507fd9478d16a542e4f1e Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Mon, 3 Dec 2018 17:52:07 -0800 Subject: iov_iter: pass void csum pointer to csum_and_copy_to_iter The single caller to csum_and_copy_to_iter is skb_copy_and_csum_datagram and we are trying to unite its logic with skb_copy_datagram_iter by passing a callback to the copy function that we want to apply. Thus, we need to make the checksum pointer private to the function. Acked-by: David S.
