Subject: [PATCH net-next 1/2] ipv6: Remove __ipv6_only_sock().
Date: Wed, 20 Apr 2022 10:58:50 +0900 [thread overview]
Message-ID: <20220420015851.50237-2-kuniyu@amazon.co.jp> (raw)
In-Reply-To: <20220420015851.50237-1-kuniyu@amazon.co.jp>
Since commit 9fe516ba3fb2 ("inet: move ipv6only in sock_common"),
ipv6_only_sock() and __ipv6_only_sock() are the same macro. Let's
remove the one.
