From 51f3d02b980a338cd291d2bc7629cdfb2568424b Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 5 Nov 2014 16:46:40 -0500 Subject: net: Add and use skb_copy_datagram_msg() helper. This encapsulates all of the skb_copy_datagram_iovec() callers with call argument signature "skb, offset, msghdr->msg_iov, length". When we move to iov_iters in the networking, the iov_iter object will sit in the msghdr. Having a helper like this means there will be less places to touch during that transformation. Based upon descriptions and patch from Al Viro. Signed-off-by: David S.
