函数名称：rht_head_hashfn

函数原型：static inline unsigned int rht_head_hashfn(struct rhashtable *ht, const struct bucket_table *tbl, const struct rhash_head *he, const struct rhashtable_params params)

返回类型：unsigned int

参数：

类型参数名称
struct rhashtable *ht
const struct bucket_table *tbl
const struct rhash_head *he
const struct rhashtable_paramsparams
168  ptr等于rht_obj(ht, he)
170  返回:如果此条件成立可能性大(为编译器优化)(obj_hashfn)则rht_bucket_index(tbl, obj_hashfn(ptr, key_len ? : key_len, hash_rnd))否则rht_key_hashfn(ht, tbl, ptr + key_offset, params)
