Subject: [PATCH v2 bpf-next 5/7] libbpf: move bpf_{helpers,endian,tracing}.h into libbpf
Date: Wed, 2 Oct 2019 14:50:39 -0700	[thread overview]
Message-ID: <20191002215041.1083058-6-andriin@fb.com> (raw)
In-Reply-To: <20191002215041.1083058-1-andriin@fb.com>

Move bpf_helpers.h, bpf_tracing.h, and bpf_endian.h into libbpf. Ensure
they are installed along the other libbpf headers. Also, adjust
selftests and samples include path to include libbpf now.
