From a5ba671a2432e1622bccdc5d5d504138b2a37d72 Mon Sep 17 00:00:00 2001 From: Stanislav Fomichev Date: Wed, 12 Feb 2014 17:35:21 +0400 Subject: tcp: remove unused min_cwnd member of tcp_congestion_ops Commit 684bad110757 "tcp: use PRR to reduce cwin in CWR state" removed all calls to min_cwnd, so we can safely remove it. Also, remove tcp_reno_min_cwnd because it was only used for min_cwnd. Signed-off-by: Stanislav Fomichev Acked-by: Yuchung Cheng Signed-off-by: David S.
