函数名称：First-use initialization of statically allocated srcu_struct* structure

函数原型：static void check_init_srcu_struct(struct srcu_struct *ssp)

返回类型：void

参数：

类型参数名称
struct srcu_struct *ssp
232  如果非Return the state portion of a sequence number previously returned* by rcu_seq_snap() or rcu_seq_current().则返回
234  spin_lock_irqsave_rcu_node(ssp, flags)
235  如果非Return the state portion of a sequence number previously returned* by rcu_seq_snap() or rcu_seq_current().则
236  spin_unlock_irqrestore_rcu_node(ssp, flags)
237  返回
239  Initialize non-compile-time initialized fields, including the* associated srcu_node and srcu_data structures. The is_static* parameter is passed through to init_srcu_struct_nodes(), and* also tells us that ->sda has already been wired up to srcu_data.
