Subject: [PATCH net-next v5 02/12] net: tunnel: add pskb_inet_may_pull_reason() helper
Date: Sun, 6 Oct 2024 14:56:06 +0800 [thread overview]
Message-ID: <20241006065616.2563243-3-dongml2@chinatelecom.cn> (raw)
In-Reply-To: <20241006065616.2563243-1-dongml2@chinatelecom.cn>
Introduce the function pskb_inet_may_pull_reason() and make
pskb_inet_may_pull a simple inline call to it. The drop reasons of it just
come from pskb_may_pull_reason().
