Subject: [PATCH v13 13/32] perf kmem: Don't pass evsel with sample
Date: Tue, 12 May 2026 15:29:42 -0700	[thread overview]
Message-ID: <20260512223001.2952848-14-irogers@google.com> (raw)
In-Reply-To: <20260512223001.2952848-1-irogers@google.com>

The sample contains the evsel and so it is unnecessary to pass the
evsel as well.
