Currently, a CONFIG_PREEMPT_NONE=y kernel substitutes normal RCU for RCU Tasks. Unless that kernel builds rcutorture, whether built-in or as a module, in which case RCU Tasks is (unnecessarily) used. This both increases kernel size and increases the complexity of certain tracing operations. This commit therefore decouples the presence of rcutorture from the presence of RCU Tasks. However, there is a need to select CONFIG_TASKS_RCU for testing purposes. Except that casual users must not be bothered with questions -- for them, this needs to be fully automated. There is thus a CONFIG_FORCE_TASKS_RCU that selects CONFIG_TASKS_RCU, is user-selectable, but which depends on CONFIG_RCU_EXPERT. [ paulmck: Apply kernel test robot feedback. ] Signed-off-by: Paul E.
