PS4, Line 152:       std::vector<BlockBloomFilterInner>&& bfs,
> Here and below you don't need the rvalue reference; could just pass std::ve
I understand but using rvalue reference as type for bfs forces caller to pass 
rvalue(using std::move or directly) and avoid the costly copy of a vector by 
mistake. Hence this is deliberate.

> Good point.
Thanks for the tip. Done.

Done

Intent was to move the memset() outside of InitInternal() but missed removing 
that line from InitInternal(). Fixed.
