Subject: [PATCH v13 06/32] perf lock: Only pass sample to handlers
Date: Tue, 12 May 2026 15:29:35 -0700 [thread overview]
Message-ID: <20260512223001.2952848-7-irogers@google.com> (raw)
In-Reply-To: <20260512223001.2952848-1-irogers@google.com>
The evsel is within the sample and so only the sample needs to be
passed. Remove the parameter and fix call site.
