Subject: [Patch bpf-next v6 8/8] skmsg: get rid of sk_psock_bpf_run()
Date: Fri, 19 Feb 2021 21:29:24 -0800
Message-ID: <20210220052924.106599-9-xiyou.wangcong@gmail.com> (raw)
In-Reply-To: <20210220052924.106599-1-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.
