Subject: [PATCH v2 3/5] selftests/bpf: add default bpftool built by selftests to PATH
Date: Fri, 20 Aug 2021 09:55:55 +0800	[thread overview]
Message-ID: <20210820015556.23276-4-lizhijian@cn.fujitsu.com> (raw)
In-Reply-To: <20210820015556.23276-1-lizhijian@cn.fujitsu.com>

For 'make run_tests':
selftests will build bpftool into tools/testing/selftests/bpf/tools/sbin/bpftool
by default.
