So to solve these inclusion problem, the solution is to add bits to maintain the line state. My question is though, wouldn't the increase in bits pose a significant overhead for the already small L2 cache?

@sss It does add overhead, but considering that a cache line holds holds 64 bytes, or 512 bits, the few extra metadata bits aren't much to worry about, in this case, less than half a percent.
