From: Ilpo Järvinen Date: Thu, 31 May 2007 07:16:47 +0000 (+0300) Subject: [TCP]: Remove num_acked>0 checks from cong.ctrl mods pkts_acked X-Git-Tag: v2.6.24-rc1~1454^2~824 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=35e8694198ba94b62df8aa35fa6e52a1cfb86df2;p=platform%2Fkernel%2Flinux-exynos.git [TCP]: Remove num_acked>0 checks from cong.ctrl mods pkts_acked 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.
