Subject: [PATCH net-next 4/9] netfilter: Reorder fields in 'struct nf_conntrack_expect'
Date: Thu, 18 May 2023 12:07:54 +0200 [thread overview]
Message-ID: <20230518100759.84858-5-fw@strlen.de> (raw)
In-Reply-To: <20230518100759.84858-1-fw@strlen.de>
From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
Group some variables based on their sizes to reduce holes.
On x86_64, this shrinks the size of 'struct nf_conntrack_expect' from 264
to 256 bytes.
This structure deserve a dedicated cache, so reducing its size looks nice.
