Hey Linus,

This contains fixes for this merge window:

afs:

- Fix setting of the server responding flag.

- Remove unused struct afs_address_list and afs_put_address_list() function.

- Fix infinite loop because of unresponsive servers.

- Ensure that afs_retry_request() function is correctly added to the
  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
  iov_iter_advance().

  cachefiles.

pidfs:

- Correctly handle accessing another task's pid namespace.
