NAME
       seq_hlist_next_rcu - move to the next position of the hlist protected by RCU

SYNOPSIS
       struct hlist_node * seq_hlist_next_rcu(void * v, struct hlist_head * head, loff_t * ppos);

ARGUMENTS
       v
	   the current iterator

       head
	   the head of the hlist

       ppos
	   the current position

DESCRIPTION
       Called at seq_file->op->next.

       This list-traversal primitive may safely run concurrently with the _rcu list-mutation primitives such as hlist_add_head_rcu as long as the
       traversal is guarded by rcu_read_lock.
