7df20ca4 33/* Comment :
34 * Mathieu Desnoyers
35 * usertrace is there only to be able to update the current CPU of the
36 * usertraces when there is a schedchange. it is a way to link the ProcessState
37 * to the associated usertrace. Link only created upon thread creation.
38 *
39 * The cpu id is necessary : it gives us back the current ProcessState when we
40 * are considering data from the usertrace.
