Subject: [bpf-next v3 06/12] selftests/bpf: Make sure that preexisting tests for perf event work
Date: Mon, 8 Jul 2019 18:31:15 +0200 [thread overview]
Message-ID: <20190708163121.18477-7-krzesimir@kinvolk.io> (raw)
In-Reply-To: <20190708163121.18477-1-krzesimir@kinvolk.io>
We are going to introduce a test run implementation for perf event in
a later commit and it will not allow passing any data out or ctx out
to it, and requires their sizes to be specified to zero. To avoid test
failures when the feature is introduced, override the data out size to
zero. That will also cause NULL buffer to be sent to the kernel.
