Subject: [PATCH 2/2] perf evsel: Use evsel__name_is() helper
Date: Thu, 28 Mar 2024 13:58:57 +0800 [thread overview]
Message-ID: <20240328055857.383180-2-yangjihong@bytedance.com> (raw)
In-Reply-To: <20240328055857.383180-1-yangjihong@bytedance.com>
Code cleanup, replace strcmp(evsel__name(evsel, {NAME})) with
evsel__name_is() helper.
No functional change.
