Subject: [PATCH 1/5] bpf-cgroup: remove unused exports
Date: Tue, 21 Apr 2020 19:15:35 +0200	[thread overview]
Message-ID: <20200421171539.288622-2-hch@lst.de> (raw)
In-Reply-To: <20200421171539.288622-1-hch@lst.de>

Except for a few of the networking hooks called from modular ipv4 or
ipv6 code, all of hooks are just called from guaranteed to be built-in
code.
