afs:

- Fix setting of the server responding flag.

- Remove unused struct afs_address_list and afs_put_address_list() function.

  afs_req_ops netfs operations table.

netfs:

- Fix netfs_folio tracepoint handling to handle NULL mappings.

- Add a missing folio_queue API documentation.

- Ensure that netfs_write_folio() correctly advances the iterator via
