- 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().
