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. Signed-off-by: Paul E.
