Subject: An alternative for tasklist_lock in a module?

Hi,

(for learning purposes) I would like to iterate through all the tasks
in a module and output different information about them. For this task
I need to lock the list of all tasks (need I?). I've seen some example
in the kernel code which lock tasklist_lock. However this symbol
cannot be used by modules. Its export was removed by
c59923a15c12d2b3597af913bf234a0ef264a38b commit.

Is there any other way I can lock the list of tasks then? Or I'm supposed
not to use this list at all?

Thanks
