From 35e8694198ba94b62df8aa35fa6e52a1cfb86df2 Mon Sep 17 00:00:00 2001 From: Ilpo Järvinen Date: Thu, 31 May 2007 10:16:47 +0300 Subject: [TCP]: Remove num_acked>0 checks from cong.ctrl mods pkts_acked MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is no need for such check in pkts_acked because the callback is not invoked unless at least one segment got fully ACKed (i.e., the snd_una moved past skb's end_seq) by the cumulative ACK's snd_una advancement.
