Subject: [PATCH 2/3] perf tools: Check vmlinux/kallsyms arguments in all tools
Date: Mon, 18 Oct 2021 14:48:42 +0100	[thread overview]
Message-ID: <20211018134844.2627174-3-james.clark@arm.com> (raw)
In-Reply-To: <20211018134844.2627174-1-james.clark@arm.com>

Only perf report checked the validity of these arguments so apply the
same check to all tools that read them for consistency.
