failure\n\nnetfs_prepare_read_iterator() batches readahead folios in put_batch so that\nthe folio references can be dropped after the I/O iterator has been\nprepared.\n\nIf rolling_buffer_load_from_ra() fails after earlier folios have been\nbatched, the function returns immediately and leaves those references held.\nRelease the batch before returning the error.","state":0,"publishedAt":"2026-09-04T17:11:12.499+00:00","modifiedAt":"2026-10-21T12:47:12.43+00:00","affected":[{"ecosystem":"Vendor
