From 4edf16b72c57bb0faad5da143f812384df0c43f6 Mon Sep 17 00:00:00 2001 From: KP Singh Date: Mon, 30 Mar 2020 22:40:59 +0200 Subject: [PATCH] bpf, lsm: Make BPF_LSM depend on BPF_EVENTS LSM and tracing programs share their helpers with bpf_tracing_func_proto which is only defined (in bpf_trace.c) when BPF_EVENTS is enabled. Instead of adding __weak symbol, make BPF_LSM depend on BPF_EVENTS so that both tracing and LSM programs can actually share helpers.
