Subject: [PATCH v13 08/32] perf db-export: Remove evsel from struct export_sample
Date: Tue, 12 May 2026 15:29:37 -0700	[thread overview]
Message-ID: <20260512223001.2952848-9-irogers@google.com> (raw)
In-Reply-To: <20260512223001.2952848-1-irogers@google.com>

As the sample contains the evsel avoid the duplication. Remove the
evsel from db_export__sample as it can also read from the sample.
