Name:Snapshot the ->dynticks counter with full ordering so as to allow* stable comparison of this counter with past and future snapshots.
Proto:int rcu_dynticks_snap(struct rcu_data *rdp)
Type:int
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct rcu_data * | rdp |
| 310 | snap = atomic_add_return(0, & Even value for idle, else odd. ) |
| 312 | Return snap & ~Steal a bit from the bottom of ->dynticks for idle entry/exit* control. Initially this is for TLB flushing. |
| Name | Describe |
|---|---|
| rcu_dynticks_in_eqs_since | Return true if the CPU corresponding to the specified rcu_data* structure has spent some time in an extended quiescent state since* rcu_dynticks_snap() returned the specified snapshot. |
| dyntick_save_progress_counter | Snapshot the specified CPU's dynticks counter so that we can later* credit them with an implicit quiescent state. Return 1 if this CPU* is in dynticks idle mode, which is an extended quiescent state. |
| rcu_boot_init_percpu_data | Do boot-time initialization of a CPU's per-CPU RCU data. |
