From: Xuanqiang Luo <redacted> rt_flush_dev() replaces rt->dst.dev with blackhole_netdev on uncached routes. The field is also exposed as dst.dev_rcu, and existing readers use dst_dev_rcu(). Use rcu_assign_pointer() for the replacement, as dst_dev_put() already does for the same field. Signed-off-by: Xuanqiang Luo <redacted>
