Hi zusammen,
interessante Diskussion
Im Buch "Operating System Concepts" von Abraham Silberschatz (auch ein gutes OS Buch) heißt es dazu:
"... assume, we have three processes, L, M, H, whose priorities follow the order L < M < H. Assume that process H requires resource R, which is currently being accessed by process L. Ordinarily, process H would wait for L to finish using resource R. However, now suppose that process M becomes runnable, thereby preempting process L. Indirectly, a process with a lower priority - process M - has affected how long process H must wait for L to relinquish resource R. This problem is known as priority inversion. It occurs only in systems with more than two priorities."
