7df20ca4 36/* Comment :
37 * Mathieu Desnoyers
38 * usertrace is there only to be able to update the current CPU of the
39 * usertraces when there is a schedchange. it is a way to link the ProcessState
40 * to the associated usertrace. Link only created upon thread creation.
41 *
42 * The cpu id is necessary : it gives us back the current ProcessState when we
43 * are considering data from the usertrace.
