Hi, few days ago, I asked you for a method to traverse the task list "atomically", and some of you pointed me out to read_lock(&tasklist_lock), which I found it the right solution. But I forgot to mention I am outside the kernel, I am writing a kernel module I mean. And those symbols aren't exported. After some searches, I found rcu_read_lock() could do the job, and now I want to confirm this, please. Thank you very much. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
