Subject: [PATCH -next] net/ipv4/route.c: remove superfluous header files from
 route.c
Date: Mon, 20 Sep 2021 19:31:37 +0800
Message-ID: <20210920113137.25121-1-liumh1@shanghaitech.edu.cn>
X-Mailer: git-send-email 2.25.1
MIME-Version: 1.0
X-Originating-IP: [10.15.44.220]
Precedence: bulk
List-ID: <netdev.vger.kernel.org>
X-Mailing-List: netdev@vger.kernel.org
X-Patchwork-Delegate: kuba@kernel.org

route.c hasn't use any macro or function declared in uaccess.h, types.h,
string.h, sockios.h, times.h, protocol.h, arp.h and l3mdev.h. Thus, these
files can be removed from route.c safely without affecting the compilation
of the net module.
