函数名称：smk_list_swap_rcu - swap public list with a private one in RCU-safe way* The caller must hold appropriate mutex to prevent concurrent modifications* to the public list

函数原型：static void smk_list_swap_rcu(struct list_head *public, struct list_head *private)

返回类型：void

参数：

类型参数名称
struct list_head *public
struct list_head *private
1899  如果链表为空则
1900  list_splice_init_rcu - splice an RCU-protected list into an existing list,* designed for stacks.*@list: the RCU-protected list to splice*@head: the place in the existing list to splice the first list into
1901  否则
1903  first等于链表后项
1904  last等于链表前项
1907  链表后项等于public
1908  链表前项等于public
1909  cu_assign_pointer() - assign to RCU-protected pointer*@p: pointer to assign to*@v: value to assign (publish)* Assigns the specified value to the specified RCU-protected* pointer, ensuring that any concurrent RCU readers will see* any prior initialization(链表后项, 链表后项)
1910  链表前项等于链表前项
1912  Wait for a grace period to elapse. But it is illegal to invoke* synchronize_rcu() from within an RCU read-side critical section.* Therefore, any legal call to synchronize_rcu() is a quiescent
1916  链表后项等于first
1917  链表前项等于last
1918  链表前项等于private
1919  链表后项等于private
