Hi,

For learning purposes I would like to iterate through all the processes in a module and output different information about them. For What information did you want to get for processes? /proc/PID/xxx is not enough for u? this task I need to lock the list of all tasks. I've seen some example in the kernel code which lock tasklist_lock. However this symbol tasklist_lock had been deprecated for a long time. Maybe rcu_read_lock could help u. cannot be used by modules. Is there any other way I can lock the list of tasks then?

Thanks

Hi, thank you for your reply. It would be enough, however I want to do some kernel programming. Regards, Roman
