Paul E. McKenney b0afa0f056 rcu-tasks: Provide boot parameter to delay IPIs until late in grace period ... This commit provides a rcupdate.rcu_task_ipi_delay kernel boot parameter that specifies how old the RCU tasks trace grace period must be before the grace-period kthread starts sending IPIs. This delay allows more tasks to pass through rcu_tasks_qs() quiescent states, thus reducing (or even eliminating) the number of IPIs that must be sent. On a short rcutorture test setting this kernel boot parameter to HZ/2 resulted in zero IPIs for all 877 RCU-tasks trace grace periods that elapsed during that test. Signed-off-by: Paul E.
