From f78e73e27fdeab6f9317667f7e9676b59c1ec1fb Mon Sep 17 00:00:00 2001 From: Soheil Hassas Yeganeh Date: Mon, 19 Sep 2016 23:39:08 -0400 Subject: [PATCH] tcp: cdg: rename struct minmax in tcp_cdg.c to avoid a naming conflict The upcoming change "lib/win_minmax: windowed min or max estimator" introduces a struct called minmax, which is then included in include/linux/tcp.h in the upcoming change "tcp: use windowed min filter library for TCP min_rtt estimation". This would create a compilation error for tcp_cdg.c, which defines its own minmax struct. To avoid this naming conflict (and potentially others in the future), this commit renames the version used in tcp_cdg.c to cdg_minmax.
