There's a much more shrewd method to achieve the same, via 2 lines total patch: Change the name of CONFIG_CLASSIC_RCU to something else such as CONFIG_FLAT_RCU. That does all the magic and more: all configs will default to tree-rcu - not just defconfigs! Agreed? [ I think the gene of laziness is probably more developed in my genome than in yours. It is a very useful trait ;-) ] Ingo
