Name:Compute the mask of online CPUs for the specified rcu_node structure.* This will not be stable unless the rcu_node structure's ->lock is* held, but the bit corresponding to the current CPU will be stable* in most contexts.
Proto:unsigned long rcu_rnp_online_cpus(struct rcu_node *rnp)
Type:unsigned long
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct rcu_node * | rnp |
| 193 | Return READ_ONCE(ginning of each grace period. ) |
| Name | Describe |
|---|---|
| rcu_implicit_dynticks_qs | Return true if the specified CPU has passed through a quiescent* state by virtue of being in or having passed through an dynticks* idle state since the last call to dyntick_save_progress_counter()* for this same CPU, or by virtue of having been offline. |
