From 1793a588888235f3943daa1fd85ce635f3d6e1a6 Mon Sep 17 00:00:00 2001 From: Neels Hofmeyr Date: Mon, 2 May 2016 15:55:22 +0200 Subject: paging: change subscr_paging_cb() into subscr_rx_paging_response() Remove one layer of callback indirection in paging. When a paging response arrives, we always want to first secure the connection, thus a fixed subscr_rx_paging_response() function is more appropriate and avoids having to store a cbfn. The actual actions to be taken upon successful paging are of course still in callback functions stored with each subscriber. Remove paging_request_stop() call from subscr_paging_dispatch(), which stops paging on all BTSs, which is not the responsibility of libmsc.
