Subject: [PATCH 22/30] netfilter: nf_tables: Pass struct net in nft_pktinfo
Date: Tue, 22 Sep 2015 11:14:12 +0200 [thread overview]
Message-ID: <1442913260-3925-23-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1442913260-3925-1-git-send-email-pablo@netfilter.org>
From: "Eric W. Biederman" <ebiederm@xmission.com>
nft_pktinfo is passed on the stack so this does not bloat any in core
data structures.
By centrally computing this information this makes maintence of the code
simpler, and understading of the code easier.
