函数名称：hashtable_replace_fast - replace an object in hash table*@ht: hash table*@obj_old: pointer to hash head inside object being replaced*@obj_new: pointer to hash head inside object which is new*@params: hash table parameters* Replacing an object doesn't

函数原型：static inline int rhashtable_replace_fast(struct rhashtable *ht, struct rhash_head *obj_old, struct rhash_head *obj_new, const struct rhashtable_params params)

1215  _read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other
1217  tbl等于rht_dereference_rcu(tbl, ht)
1224  当err等于Internal function, please use rhashtable_replace_fast() instead 且tbl等于rht_dereference_rcu(future_tbl, ht)循环
1229  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
