Subject: [Patch bpf-next v7 8/9] skmsg: get rid of sk_psock_bpf_run()
Date: Tue, 23 Feb 2021 10:49:33 -0800 [thread overview]
Message-ID: <20210223184934.6054-9-xiyou.wangcong@gmail.com> (raw)
In-Reply-To: <20210223184934.6054-1-xiyou.wangcong@gmail.com>
From: Cong Wang <cong.wang@bytedance.com>
It is now nearly identical to bpf_prog_run_pin_on_cpu() and
it has an unused parameter 'psock', so we can just get rid
of it and call bpf_prog_run_pin_on_cpu() directly.
