Subject: [PATCH 1/5] bpf-cgroup: remove unused exports
Date: Fri, 24 Apr 2020 08:43:34 +0200 [thread overview]
Message-ID: <20200424064338.538313-2-hch@lst.de> (raw)
In-Reply-To: <20200424064338.538313-1-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.
