From: "Paul E. McKenney" <[email protected]> RCU_FANOUT_LEAF's range and default values depend on the value of RCU_FANOUT, which at the time seemed like a cute way to save two lines of Kconfig code. However, adding a dependency from both of these Kconfig parameters on RCU_EXPERT requires that RCU_FANOUT_LEAF operate correctly even if RCU_FANOUT is undefined. This commit therefore allows RCU_FANOUT_LEAF to take on the full range of permitted values, even in cases where RCU_FANOUT is undefined.
