samples/bpf: raw tracepoint test add empty raw_tracepoint bpf program to test overhead similar to kprobe and traditional tracepoint tests Signed-off-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> 2018-03-29 03:05:39 +08:00			`// SPDX-License-Identifier: GPL-2.0`

samples/bpf: Use consistent include paths for libbpf Fix all files in samples/bpf to include libbpf header files with the bpf/ prefix, to be consistent with external users of the library. Also ensure that all includes of exported libbpf header files (those that are exported on 'make install' of the library) use bracketed includes instead of quoted. To make sure no new files are introduced that doesn't include the bpf/ prefix in its include, remove tools/lib/bpf from the include path entirely, and use tools/lib instead.
