函数名称：__rhashtable_walk_find_next - Find the next element in a table (or the first* one in case of a new walk).*@iter: Hash table iterator* Returns the found object or NULL when the end of the table is reached.* Returns -EAGAIN if resize event occurred.

函数原型：static void *__rhashtable_walk_find_next(struct rhashtable_iter *iter)

返回类型：void

类型参数名称
struct rhashtable_iter *iter
782  tbl等于tbl
783  list等于list
784  ht等于ht
785  p等于p
786  rhlist等于rhlist
788  如果非tbl则返回:NULL
791  以slot小于size循环
792  skip等于skip
795  如果rhlist则
796  list等于container_of - cast a member of a structure out to the containing structure*@ptr: the pointer to the member.*@type: the type of the container struct this is embedded in.*@member: the name of the member within the struct.(p, structrhlist_head, rhead)
798  循环
803  当list循环
805  继续下一循环
807  如果非skip则退出
809  skip自减
812  :
813  如果非rht_is_a_nulls(p)则
814  skip自加
815  p等于p
816  list等于list
817  返回:rht_obj(ht, rhlist ? & rhead : p)
820  skip等于0
823  p = NULL
826  smp_rmb()
828  tbl等于rht_dereference_rcu(future_tbl, ht)
829  如果tbl则
830  slot等于0
