Does 28 U.S.C. § 1291 give a federal court of appeals jurisdiction to review a district court's decision that a habeas petitioner's motion under Rule 60(b)(6) of the Federal Rules of Civil Procedure is not a true Rule 60(b) motion if, in the same order, the district court also transfers to the court of appeals under 28 U.S.C. § 1631 what it construes as a second-or-successive habeas petition?

Does the court of appeals have jurisdiction to review a district court's decision that a habeas petitioner's Rule 60(b)(6) motion is an unauthorized second-or-successive habeas petition?
