Subject: [PATCH nf-next v2 11/11] net: remove obsolete members from struct net
Date: Thu,  1 Apr 2021 16:11:14 +0200	[thread overview]
Message-ID: <20210401141114.24712-12-fw@strlen.de> (raw)
In-Reply-To: <20210401141114.24712-1-fw@strlen.de>

all have been moved to generic_net infra. On x86_64, this reduces
struct net size from 70 to 63 cache lines (4480 to 4032 byte).
