From b238e187b4a2d3b54d80aec05a9cab6466b79dde Mon Sep 17 00:00:00 2001 From: Eduard Zingerman Date: Mon, 9 Dec 2024 20:10:54 -0800 Subject: bpf: refactor bpf_helper_changes_pkt_data to use helper number Use BPF helper number instead of function pointer in bpf_helper_changes_pkt_data(). This would simplify usage of this function in verifier.c:check_cfg() (in a follow-up patch), where only helper number is easily available and there is no real need to lookup helper proto.
