返回类型：int

参数：

类型参数名称
struct rhashtable *ht
struct test_obj *obj
const struct rhashtable_paramsparams
118  retries等于负1, enomem_retries等于0
120  循环
121  retries自加
122  cond_resched()
123  err等于hashtable_insert_fast - insert object into hash table*@ht: hash table*@obj: pointer to hash head inside object*@params: hash table parameters* Will take the per bucket bitlock to protect against mutual mutations* on the same bucket
124  如果err恒等于负ENOMEM且enomem_retry则
125  enomem_retries自加
126  err等于负EBUSY
128  当err恒等于负EBUSY循环
130  如果enomem_retries则打印信息(" %u insertions retried after -ENOMEM\n", enomem_retries)
134  返回:如果err否则retries
