[PATCH v2 1/2] rcu: Enable rcu_normal_wake_from_gp on small systems

2025-06-11 Thread Uladzislau Rezki (Sony)
Automatically enable the rcu_normal_wake_from_gp parameter on systems with a small number of CPUs. The activation threshold is set to 16 CPUs. This helps to reduce a latency of normal synchronize_rcu() API by waking up GP-waiters earlier and decoupling synchronize_rcu() callers from regular callba
