函数名称：test_rht_lookup

函数原型：static int __init test_rht_lookup(struct rhashtable *ht, struct test_obj *array, unsigned int entries)

返回类型：int

参数：

类型参数名称
struct rhashtable *ht
struct test_obj *array
unsigned intentries
142  以i小于entries循环
144  expected等于非i与2的模
145  struct test_obj_val key = {id = i, }
149  如果id恒等于TEST_INSERT_FAIL则expected = false
152  obj等于hashtable_lookup_fast - search hash table, without RCU read lock*@ht: hash table*@key: the pointer to the key*@params: hash table parameters* Computes the hash value for the key and traverses the bucket chain looking* for a entry with an identical key
154  如果expected且非obj则
155  打印警告信息("Test failed: Could not find key %u\n", id)
156  返回:负ENOENT
157  否则如果非expected且obj则
158  打印警告信息("Test failed: Unexpected entry found for key %u\n", id)
160  返回:负EEXIST
161  否则如果expected且obj则
162  如果id不等于i则
163  打印警告信息("Test failed: Lookup value mismatch %u!=%u\n", id, i)
165  返回:负EINVAL
169  cond_resched_rcu()
172  返回:0
