Hi,
Note that "conn_client:" isn't a suitable tag for the subject. You should use
"rxrpc:" instead.
How did you find this by the way? You shouldn't get a NULL pointer there.
Either the call is waiting for a channel to be assigned (in which case the
condition on:
if (!list_empty(&call->chan_wait_link)) {
will be true) or it should have been assigned a channel, in which case chan
will not be NULL.
Note that the function takes the lock under which this is managed
(conn->channel_lock) across this, so it shouldn't change.
Even __rxrpc_disconnect_call(), which is called to implicitly close out a call
that gets superseded on its channel, doesn't stop
rxrpc_disconnect_client_call() from finding the channel.
