Subject: [PATCH bpf-next v2 09/10] selftests: Remove tools/lib/bpf from include path
Date: Wed, 15 Jan 2020 15:12:58 +0100
Message-ID: <157909757860.1192265.1725940708658939712.stgit@toke.dk> (raw)
In-Reply-To: <157909756858.1192265.6657542187065456112.stgit@toke.dk>

From: Toke Høiland-Jørgensen <toke@redhat.com>

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. To fix the original issue with
bpf_helper_defs.h being stale, change the Makefile rule to regenerate the
file in the lib/bpf dir instead of having a local copy in selftests.
