Only io_uring uses (and added) these, and we want to disallow the use of sendmsg/recvmsg for anything but regular data transfers. Use the newly added prep helper to split the msghdr copy out from the core function, to check for msg_control and msg_controllen settings. If either is set, we return -EINVAL. Acked-by: David S.
