-Subject: [PATCH] wireguard: queueing: cleanup ptr_ring in error path of
- packet_queue_init
-
-commit 130c58606171326c81841a49cc913cd354113dd9 upstream.
-
-Prior, if the alloc_percpu of packet_percpu_multicore_worker_alloc
-failed, the previously allocated ptr_ring wouldn't be freed. This commit
-adds the missing call to ptr_ring_cleanup in the error case.
