The existence of this problem has been known since the 1970s. Lampson and Redell published one of the first papers to point out the priority inversion problem. Systems such as the UNIX kernel were already addressing the problem with the splx() primitive. There is no foolproof method to predict the situation. There are however many existing solutions, of which the most common ones are: Webbe long enough to cause tasks to miss their deadlines. Priority inversion cannot be completely eliminated.
