Currently, directories cannot be fallocated, which means that the only way they get bigger is for the kernel to append blocks one by one. Therefore, if we encounter a logical block offset that is too big, we needn't bother adding it to the dblist for pass2 processing, because it's unlikely to contain a valid directory block. The code that handles extent based directories also does not add toobig blocks to the dblist. Note that we can easily cause e2fsck to fail with ENOMEM if we start feeding it really large logical block offsets, as the dblist implementation will try to realloc() an array big enough to hold it.
