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
