net/ipv6/ip6_gre.c is a case of parallel adds. include/trace/events/tcp.h is a little bit more tricky. The removal of in-trace-macro ifdefs in 'net' paralleled with moving show_tcp_state_name and friends over to include/trace/events/sock.h in 'net-next'. Signed-off-by: David S. Miller <davem@davemloft.net>
