hlist_for_each_entry_rcu - iterate over rcu list of given type
hlist_for_each_entry_rcu (tpos, pos, head, member);
tpos the type * to use as a loop counter.
pos the &struct hlist_node to use as a loop counter.
head the head for your list.
member the name of the hlist_node within the struct.
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.
