clang-16 with W=1 complains that:
+net/ipv6/udp.c:341:5: warning: no previous prototype for 'udpv6_recvmsg' [-Wmissing-prototypes]
+ 341 | int udpv6_recvmsg(struct sock *sk, struct msghdr *msg, size_t len,
+ | ^~~~~~~~~~~~~
+net/ipv6/udp.c:1335:5: warning: no previous prototype for 'udpv6_sendmsg' [-Wmissing-prototypes]
+ 1335 | int udpv6_sendmsg(struct sock *sk, struct msghdr *msg, size_t len)
+ | ^~~~~~~~~~~~~
Likewise it has similar complains about ipv4 in a subsequent patch.
