ouch!
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 ;-) ]
