7

SYNOPSIS

9       struct hlist_node * seq_hlist_start_rcu(struct hlist_head * head,
10                                               loff_t pos);

ARGUMENTS

13       head
14           the head of the hlist
15
16       pos
17           the start position of the sequence

DESCRIPTION

20       Called at seq_file->op->start.
21
22       This list-traversal primitive may safely run concurrently with the _rcu
23       list-mutation primitives such as hlist_add_head_rcu as long as the
24       traversal is guarded by rcu_read_lock.
