Subject: [PATCH v1 01/51] perf tools: Ensure evsel name is initialized
Date: Sun, 19 Feb 2023 01:27:58 -0800 [thread overview]
Message-ID: <20230219092848.639226-2-irogers@google.com> (raw)
In-Reply-To: <20230219092848.639226-1-irogers@google.com>
Use the evsel__name accessor as otherwise name may be NULL resulting
in a segv. This was observed with the perf stat shell test.
