Subject: [PATCH net-next 09/27] net: inline sock_alloc_send_skb
Date: Sun, 3 Apr 2022 14:06:21 +0100 [thread overview]
Message-ID: <02d5e2ea08dc28f3e22245c6c1110a108e576abc.1648981571.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1648981570.git.asml.silence@gmail.com>
sock_alloc_send_skb() is simple and just proxying to another function,
so we can inline it and cut associated overhead.
