The process may be rescheduled to run on different processor. Then the add_timer() function (called from schedule_next_timer in kernel/posix-timers.c) will also add the timer to the new processor because it is called from the signal handling code. So I think that it is possible that a periodic timer will be scheduled on different processors. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
