From mboxrd@z Thu Jan 1 00:00:00 1970 From: Gerrit Renker Subject: [PATCH 2/4] [PATCH v2] [TFRC]: Loss interval code needs the macros/inlines that were moved Date: Mon, 10 Dec 2007 13:11:56 +0000 Message-ID: <1197292318-29659-3-git-send-email-gerrit@erg.abdn.ac.uk> References: dccp_tfrc_loss_intervals_revised_patch_set <1197292318-29659-1-git-send-email-gerrit@erg.abdn.ac.uk> <1197292318-29659-2-git-send-email-gerrit@erg.abdn.ac.uk> Cc: dccp@vger.kernel.org, netdev@vger.kernel.org, Gerrit Renker To: acme@redhat.com Return-path: Received: from dee.erg.abdn.ac.uk ([139.133.204.82]:38184 "EHLO erg.abdn.ac.uk" rhost-flags-OK-OK-OK-FAIL) by vger.kernel.org with ESMTP id S1752598AbXLJNNc (ORCPT ); Mon, 10 Dec 2007 08:13:32 -0500 In-Reply-To: <1197292318-29659-2-git-send-email-gerrit@erg.abdn.ac.uk> Sender: netdev-owner@vger.kernel.org List-ID: This moves the inlines (which were previously declared as macros) back into packet_history.h since the loss detection code needs to be able to read entries from the RX history in order to create the relevant loss entries: it needs at least tfrc_rx_hist_loss_prev() and tfrc_rx_hist_last_rcv(), which in turn require the definition of the other inlines (macros).
