SYNOPSIS

10       struct hlist_node * seq_hlist_next_rcu(void * v,
11                                              struct hlist_head * head,
12                                              loff_t * ppos);
13

ARGUMENTS

15       v
16           the current iterator
17
18       head
19           the head of the hlist
20
21       ppos
22           the current position

DESCRIPTION

25       Called at seq_file->op->next.
26
27       This list-traversal primitive may safely run concurrently with the _rcu
28       list-mutation primitives such as hlist_add_head_rcu as long as the
29       traversal is guarded by rcu_read_lock.
