From:YueHaibing<> Subject: [PATCH] netdevsim: Fix error handling in nsim_fib_init and neim_fib_exit Date: Mon, 8 Jun 2020 15:13:40 +0800
In nsim_fib_init(),if register_fib_notifier failed,nsim_fib_net_ops should be unregistered before return;
In nsim_fib_exit(),unregister_fib_notifier should be called before nsim_fib_net_ops be unregistered, otherwise may cause use-after-free
