David Ahern 7dd73168e2 ipv6: Always allocate pcpu memory in a fib6_nh ... A recent commit had an unintended side effect with reject routes: rt6i_pcpu is expected to always be initialized for all fib6_info except the null entry. The commit mentioned below skips it for reject routes and ends up leaking references to the loopback device. For example, ip netns add foo ip -netns foo li set lo up ip -netns foo -6 ro add blackhole 2001:db8:1::1 ip netns exec foo ping6 2001:db8:1::1 ip netns del foo ends up spewing: unregister_netdevice: waiting for lo to become free. Usage count = 3 The fib_nh_common_init is not needed for reject routes (no ipv4 caching or encaps), so move the alloc_percpu_gfp after it and adjust the goto label.
