Subject: [PATCH 14/14] net: inline sock_alloc_send_skb
Date: Tue, 11 Jan 2022 01:21:47 +0000	[thread overview]
Message-ID: <00f1789794462df0bd2f23bd9672cc7ddc740494.1641863490.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1641863490.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.
