SEQ_HLIST_NEXT_RCU(9)                     The Linux VFS                     SEQ_HLIST_NEXT_RCU(9)



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.
