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. |
