The recent change to make insert range an atomic operation used the incorrect transaction rolling mechanism. The explicit transaction roll does not finish deferred operations. This means that intents for rmapbt updates caused by extent shifts are not logged until the final transaction commits. Thus if a crash occurs during an insert range, log recovery might leave the rmapbt in an inconsistent state. This was discovered by repeated runs of generic/455. Update insert range to finish dfops on every shift iteration. This is similar to collapse range and ensures that intents are logged with the transactions that make associated changes.
