Our LLC must maintain inclusivity with higher levels of caches in the system. What this means is that the next level cache in our system will be a subset of our LLC. For example, everything in L2 must be in our LLC, assuming L2 is the next higher level in the hierarchy. If we evict a line in the LLC that is also in L2, we will need to simulate the eviction of that data in L2 as well.
