3. [15pts] What is priority inversion? In a priority-driven system where all tasks are preemptable and that only need the processor to run, will priority inversion occur? Among the four protocols, i.e., nonpreemtive critical section protocol, priority inheritance protocol, priority ceiling protocol, and stack-sharing priority ceiling protocol, which protocols prevent priority inversion? 3.
