-       Applications that use call_rcu() are required to invoke
-       call_rcu_after_fork_child() from the child process after a
-       successful fork() system call that is not followed by exec().
+       Applications that use call_rcu() and that fork() without
+       doing an immediate exec() must take special action.  The parent
+       must invoke call_rcu_before_fork() before the fork() and
+       call_rcu_after_fork_parent() after the fork().  The child
+       process must invoke call_rcu_after_fork_child().
+       These three APIs are suitable for passing to pthread_atfork().
