Subject: [PATCH 5.7 08/20] net: udp: Fix wrong clean up for IS_UDPLITE macro
Date: Thu, 30 Jul 2020 10:03:58 +0200
Message-ID: <20200730074420.923736178@linuxfoundation.org> (raw)
In-Reply-To: <20200730074420.533211699@linuxfoundation.org>

From: Miaohe Lin <linmiaohe@huawei.com>

[ Upstream commit b0a422772fec29811e293c7c0e6f991c0fd9241d ]

We can't use IS_UDPLITE to replace udp_sk->pcflag when UDPLITE_RECV_CC is
checked.

Fixes: b2bf1e2659b1 ("[UDP]: Clean up for IS_UDPLITE macro")
