The code I currently have here has changed. Is has grown a nice comment:

/*
* find_task_by_pid() does not take the tasklist lock anymore
* but is nicely RCU locked - hence is a pretty resilient
* thing to use:
*/
return find_task_by_pid(tid);

I updated the comment appropriately
(s/find_task_by_pid/find_task_by_pid_ns/). Please check that this was
true.
