From 73d97508ab11a4986752e22e62b3c49213272c0f Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 18 Jul 2023 16:20:49 +0000 Subject: [PATCH] tcp: tcp_enter_quickack_mode() should be static [ Upstream commit 03b123debcbc8db987bda17ed8412cc011064c22 ] After commit d2ccd7bc8acd ("tcp: avoid resetting ACK timer in DCTCP"), tcp_enter_quickack_mode() is only used from net/ipv4/tcp_input.c.
