Subject: [PATCH 2/7] perf test: Use skip in vmlinux kallsyms
Date: Thu, 12 May 2022 21:05:14 -0700	[thread overview]
Message-ID: <20220513040519.1499333-3-irogers@google.com> (raw)
In-Reply-To: <20220513040519.1499333-1-irogers@google.com>

Currently failures in reading vmlinux or kallsyms result in a test
failure. However, the failure is typically permission related. Prefer to
flag these failures as skip.
