From d82068f38f0c587884b62b93d8d27d8dc84272c6 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Sun, 21 Feb 2016 15:33:15 +0000 Subject: [PATCH] tools/build: Remove bpf() run-time check at build time It is not correct to test that a syscall works on the build system's kernel. We might be building on an earlier kernel version or with security restrictions that block bpf().
