Currently the call_rcu_tasks() kthread is created upon first invocation of call_rcu_tasks(). This has the advantage of avoiding creation if there are never any invocations of call_rcu_tasks() and of synchronize_rcu_tasks(), but it requires an unreliable heuristic to determine when it is safe to create the kthread. For example, it is not safe to create the kthread when call_rcu_tasks() is invoked with a spinlock held, but there is no good way to detect this in !PREEMPT kernels. This commit therefore creates this kthread unconditionally at core_initcall() time. If you don't want this kthread created, then build with CONFIG_TASKS_RCU=n. Signed-off-by: Paul E.
