Using tasklist_lock in a module -- is there an alternative?
Hi, For learning purposes I would like to iterate through all the processes in a module and output different information about them. For 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 cannot be used by modules. Is there any other way I can lock the list of tasks then? Thanks

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
