From 1cc31ce401aef02f268e8afc34fc4aad892ac9b1 Mon Sep 17 00:00:00 2001 From: Stijn Tintel Date: Sun, 20 Feb 2022 03:32:23 +0200 Subject: [PATCH] kernel: add KERNEL_BPF_EVENTS config option This is required to use BPF maps of type BPF_MAP_TYPE_PERF_EVENT_ARRAY for sending data from BPF programs to user-space for post-processing or logging. As this symbol exposes KERNEL_BPF_KPROBE_OVERRIDE, also add a config option for it.
