> The patches are:
> 
>  (1) Add some tracepoints for logging incoming calls and monitoring
>      notifications from AF_RXRPC and data reception.
> 
>  (2) Get rid of afs_wait_mode as it didn't turn out to be as useful as
>      initially expected.  It can be brought back later if needed.  This
>      clears some stuff out that I don't then need to fix up in (4).
> 
>  (3) Allow listen(..., 0) to be used to disable listening.  This makes
>      shutting down the AFS cache manager server in the kernel much easier
>      and the accounting simpler as we can then be sure that (a) all
>      preallocated afs_call structs are relesed and (b) no new incoming
>      calls are going to be started.
> 
>      For the moment, listening cannot be reenabled.
> 
>  (4) Add refcounting to the afs_call struct to fix a potential multiple
>      release detected by static checking and add a tracepoint to follow the
>      lifecycle of afs_call objects.
