Subject: [PATCH 4/4] perf test: Simplify perf kvm record/report tests
Date: Tue, 23 Jun 2026 00:03:13 -0700	[thread overview]
Message-ID: <20260623070313.55225-5-namhyung@kernel.org> (raw)
In-Reply-To: <20260623070313.55225-1-namhyung@kernel.org>

It can now pass command line arguments to perf kvm record --host.
Let's pass 'sleep 1' directly rather than running it in background.
