parentip: convert tcp_sendmsg() to iov_iter primitives (diff)
net: switch memcpy_fromiovec()/memcpy_fromiovecend() users to copy_from_iter()
That takes care of the majority of ->sendmsg() instances - most of them via memcpy_to_msg() or assorted getfrag() callbacks. One place where we still keep memcpy_fromiovecend() is tipc - there we potentially read the same data over and over; separate patch, that... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
