Subject: [PATCH v13 16/32] perf timechart: Don't pass evsel with sample
Date: Tue, 12 May 2026 15:29:45 -0700 [thread overview]
Message-ID: <20260512223001.2952848-17-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. Add missing backtrace argument to tracepoint_handler
functions and mark them unused.
