Or just simplify the comment.
/* Prevent overflow in panic() */
Or perhaps better, fix panic() to not overflow.
- for (i = 0; i < panic_timeout * 1000; i += PANIC_TIMER_STEP) {
+ for (i = 0; i / 1000 < panic_timeout; i += PANIC_TIMER_STEP) {
you probably also want to change i to be a long long or the loop may never
terminate.
