> Support network namespacing in AF_RXRPC with the following changes:
> 
>  (1) All the local endpoint, peer and call lists, locks, counters, etc. are
>      moved into the per-namespace record.
> 
>  (2) All the connection tracking is moved into the per-namespace record
>      with the exception of the client connection ID tree, which is kept
>      global so that connection IDs are kept unique per-machine.
> 
>  (3) Each namespace gets its own epoch.  This allows each network namespace
>      to pretend to be a separate client machine.
> 
>  (4) The /proc/net/rxrpc_xxx files are now called /proc/net/rxrpc/xxx and
>      the contents reflect the namespace.
> 
> fs/afs/ should be okay with this patch as it explicitly requires the current
> net namespace to be init_net to permit a mount to proceed at the moment.  It
> will, however, need updating so that cells, IP addresses and DNS records are
> per-namespace also.
