Hi all,

After merging the net tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

net/ipv6/route.c: In function 'rt6_check':
net/ipv6/route.c:1294:43: warning: 'rt_cookie' may be used uninitialized in this function [-Wmaybe-uninitialized]
  if (!rt6_get_cookie_safe(rt, &rt_cookie) || rt_cookie != cookie)
                                           ^

Introduced by commit

  c5cff8561d2d ("ipv6: add rcu grace period before freeing fib6_node")
