From 2ec9898e9c70b93a5741af3f6af6dbceca569a47 Mon Sep 17 00:00:00 2001 From: He Fengqing Date: Wed, 31 Mar 2021 07:51:35 +0000 Subject: bpf: Remove unused parameter from ___bpf_prog_run 'stack' parameter is not used in ___bpf_prog_run() after f696b8f471ec ("bpf: split bpf core interpreter"), the base address have been set to FP reg. So consequently remove it.
