Subject: [PATCH batadv] batman-adv: fix kernel-doc for functions holding ownership of the skb
Date: Fri, 10 Jul 2026 22:31:38 +0200 [thread overview]
Message-ID: <20260710-consuming-kernel-doc-v1-1-159abdc5149f@narfation.org> (raw)
Most functions in batman-adv will take the ownership of an skb when they
receive it as argument. Their NET_RX_DROP return value is only indicating
whether there was direct visible problem while processing it. The caller
must not try to also free the skb when such a negative return code was
received.
