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