SubjectRe: [PATCH net-next 0/4] afs: Refcount afs_call struct

> (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.
