9 This document describes several list-based RCU use cases.
11 When iterating a list while holding the rcu_read_lock(), writers may
12 modify the list. The reader is guaranteed to see all of the elements
13 which were added to the list before they acquired the rcu_read_lock()
14 and are still on the list when they drop the rcu_read_unlock().
