  * policy to select from this list of LB server backends.

  * The first time the policy gets a request for a pick, a ping, or to exit the

- * lb_client_data, an internal struct meant to contain the data associated with
- * the internal communication with the LB server. This instance is created via
- * \a lb_client_data_create(). There, the call over lb_channel to pick-first

+ * idle state, \a query_for_backends_locked() is called. This function sets up
+ * and initiates the internal communication with the LB server. In particular,
+ * it's responsible for instantiating the internal *streaming* call to the LB
+ * server (whichever address from {a1..an} pick-first chose). This call is
+ * serviced by two callbacks, \a lb_on_server_status_received and \a
+ * lb_on_response_received. The former will be called when the call to the LB
+ * server completes. This can happen if the LB server closes the connection or
+ * if this policy itself cancels the call (for example because it's shutting
+ * down). If the internal call times out, the usual behavior of pick-first
+ * applies, continuing to pick from the list {a1..an}.
  *
- * Back in \a query_for_backends(), the internal *streaming* call to the LB
- * server (whichever address from {a1..an} pick-first chose) is kicked off.
- * It'll progress over the callbacks configured in \a lb_client_data_create()
- * (see the field docstrings of \a lb_client_data for more details).
- *
- * If the call fails with UNIMPLEMENTED, the original call will also fail.
- * There's a misconfiguration somewhere: at least one of {a1..an} isn't a LB
- * server, which contradicts the LB bit being set. If the internal call times
- * out, the usual behavior of pick-first applies, continuing to pick from the
- * list {a1..an}.
- *
- * Upon sucesss, a \a LoadBalancingResponse is expected in \a res_recv_cb. An
- * invalid one results in the termination of the streaming call. A new streaming
- * call should be created if possible, failing the original call otherwise.
- * For a valid \a LoadBalancingResponse, the server list of actual backends is
- * extracted. A Round Robin policy will be created from this list. There are two
