+What:   find_task_by_pid
+When:   2.6.26
+Why:    With pid namespaces, calling this funciton will return the
+        wrong task when called from inside a namespace.
+
+        The best way to save a task pid and find a task by this
+        pid later, is to find this task's struct pid pointer (or get
+        it directly from the task) and call pid_task() later.
+
+        If someone really needs to get a task by its pid_t, then
+        he most likely needs the find_task_by_vpid() to get the
+        task from the same namespace as the current task is in, but
+        this may be not so in general.
