I know, I did not want to add it either :(

Speaking of which, several of the potential fixes for the rt6_probe()
deadlock require adding even more things to the fib6_node (a linked
list which some workqueue or similar can run, or a timer, etc.).

So, I'm trying to figure out a way to get the rt6_probe() to run
outside of the per-table rwlock without adding more state to
fib6_node.
