OPINION *

In February 2016, Paul Gene Rockwood, Jr. filed a petition pursuant to 28 U.S.C. § 2241 in the United States District Court for the Middle District of Pennsylvania. By order and memorandum entered on April 28, 2017, the District Court denied Rock-wood’s § 2241 petition and declined to issue a certificate of appealability. Rockwood ' now seeks a writ of mandamus directing the District Court to act on his § 2241 petition. Because the District Court has already denied Rockwood’s § 2241 petition, we will dismiss as moot his petition for a writ of mandamus. See In re Austrian & German Holocaust Litig., 250 F.3d 156, 162-63 (2d Cir. 2001) (per curiam) (mandamus petition requesting that court of appeals compel district court action generally may be dismissed as moot upon district court’s entry of final order).
