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