We probably shouldn't use D_INFO for the hunks in ivc_on_hash and ds_iv_ns_update. Are they just temporary changes that you'll revert later? If yes, I'm fine with this PR.

D_INFO in ivc_on_hash only happened for failure case. ds_iv_ns_update only happen during leader switch, which suppose to be rare, should not be huge?

OK. I think you're the expert here.
