seq_hlist_start_head_rcu9
Start an iteration of a hlist protected by rcu
Arguments
head
the head of the hlist
pos
the start position of the sequence
Overview
Called at seq_file->op->start. Call this function if you want to print a header at the top of the output.
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.
