Or rather something like:

static inline dl_set_deadline(struct sched_dl_entity *dl_se, u64 deadline)
{
	dl_se->normal_deadline = deadline;
	/*
	 * We should never update the deadline while boosted,
	 * but if we do, make sure to not change the effective
	 * deadline until deboost.
	 */
	if (WARN_ON_ONCE(dl_se->dl_boosted))
		return;
	dl_se->deadline = dl_se->normal_deadline;
}
