Subject: [bpf-next v3 04/12] selftests/bpf: Use bpf_prog_test_run_xattr
Date: Mon, 8 Jul 2019 18:31:13 +0200 [thread overview]
Message-ID: <20190708163121.18477-5-krzesimir@kinvolk.io> (raw)
In-Reply-To: <20190708163121.18477-1-krzesimir@kinvolk.io>
The bpf_prog_test_run_xattr function gives more options to set up a
test run of a BPF program than the bpf_prog_test_run function.
We will need this extra flexibility to pass ctx data later.
