[Patch bpf-next v6 8/8] skmsg: get rid of sk_psock_bpf_run()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Cong Wang <cong.wang@xxxxxxxxxxxxx>

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.
