From: "Paul E. McKenney" <[email protected]> Currently, if a Kconfig option depends on TASKS_RCU, it conditionally does "select TASKS_RCU if PREEMPTION". This works, but requires any change in this enablement logic to be replicated across all such "select" clauses. A new NEED_TASKS_RCU Kconfig option has been created to allow this enablement logic to be in one place in kernel/rcu/Kconfig.
Therefore, make BPF select the new NEED_TASKS_RCU Kconfig option. Signed-off-by: Paul E.
