    Description

      There are no assertions that a prepare oplog entry must be majority committed before "commitTransaction" is received. This is only an understood precondition that is not enforced. With this assertion, we can guarantee collection counts are correct during rollback because it would be impossible for a "prepare" and "commit" operation to both be rolled back. See SERVER-39762.
