Inspired by 9b8ca04854fd ("ipv4: avoid quadratic behavior in FIB insertion of common address") and per-netns RTNL conversion started by Kuniyuki this week. ip_fib_check_default() can use RCU instead of a shared spinlock. fib_info_lock can be removed, RTNL is already used. fib_info_devhash[] can be removed in favor of a single pointer in net_device.
