From bd0747543b3d973df6af0f43965f58965375d524 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Sat, 8 Jun 2024 11:01:26 +0200 Subject: [PATCH] bpf: allow bpf helpers to be used into HID-BPF struct_ops Without this helpers like bpf_printk() or bpf_map_update() are not available, making anything but change of bytes impossible to do.
