Name:If there is room, assign a ->gp_seq number to any callbacks on this* CPU that have not already been assigned
Proto:static bool rcu_accelerate_cbs(struct rcu_node *rnp, struct rcu_data *rdp)
Type:bool
Parameter:
Type | Parameter | Name |
---|---|---|
struct rcu_node * | rnp | |
struct rcu_data * | rdp |
1282 | bool ret = false |
1288 | If Not Does the specified rcu_segcblist structure contain callbacks that* are still pending, that is, not yet ready to be invoked? Then Return false |
1310 | Return ret |
Name | Describe |
---|---|
rcu_accelerate_cbs_unlocked | Similar to rcu_accelerate_cbs(), but does not require that the leaf* rcu_node structure's ->lock be held |
rcu_advance_cbs | Move any callbacks whose grace period has completed to the* RCU_DONE_TAIL sublist, then compact the remaining sublists and* assign ->gp_seq numbers to any callbacks in the RCU_NEXT_TAIL* sublist. This function is idempotent, so it does not hurt to |
__note_gp_changes | Update CPU-local rcu_data state to record the beginnings and ends of* grace periods. The caller must hold the ->lock of the leaf rcu_node* structure corresponding to the current CPU, and must have irqs disabled. |
rcu_gp_cleanup | Clean up after the old grace period. |
rcu_report_qs_rdp | Record a quiescent state for the specified CPU to that CPU's rcu_data* structure. This must be called from the specified CPU. |
