Currently, the whole indexes will only be compacted 4B if compacted_4b_initial > totalidx. So, the calculated compacted_2b is worthless for that case. It may waste CPU resources. No need to update compacted_4b_initial as mkfs since it's used to fulfill the alignment of the 1st compacted_2b pack and would handle the case above. We also need to clarify compacted_4b_end here. It's used for the last lclusters which aren't fitted in the previous compacted_2b packs. Some messages are from Xiang.
