without lock, we can read the same\nvalue twice, then obtain the lock, and reclaim from there\nto two different places, but crucially reclaim the same\nentry twice, resulting in the WARN_ONCE() a little later.\nFix that by reading txq->read_ptr under lock.","state":0,"publishedAt":"2024-05-30T15:29:16.852+00:00","modifiedAt":"2026-10-15T00:42:49.285+00:00","affected":[{"ecosystem":"Vendor
