Subject: [PATCH 2/3] perf tests: Omit end of the symbol check failure for test 1
Date: Fri,  7 Jun 2013 15:37:02 +0200	[thread overview]
Message-ID: <1370612223-19188-2-git-send-email-jolsa@redhat.com> (raw)
In-Reply-To: <1370612223-19188-1-git-send-email-jolsa@redhat.com>

Omitting end of the function check failure for test 1,
since there's no way to get exact symbol end via kallsyms.

Leaving the debug message.
