Subject: [PATCH 2/3] selftests/bpf: add default bpftool built by selftests to PATH
Date: Thu, 19 Aug 2021 15:24:30 +0800 [thread overview]
Message-ID: <20210819072431.21966-2-lizhijian@cn.fujitsu.com> (raw)
In-Reply-To: <20210819072431.21966-1-lizhijian@cn.fujitsu.com>
For 'make run_tests':
selftests will build bpftool into tools/testing/selftests/bpf/tools/sbin/bpftool
by default.
