Subject: [PATCH 2/4] perf tools: Fix one of the probe events to exclude kernel
Date: Tue, 12 Aug 2014 18:04:29 +0300	[thread overview]
Message-ID: <1407855871-15024-3-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1407855871-15024-1-git-send-email-adrian.hunter@intel.com>

When probing the kernel API the kernel should be excluded
otherwise the probe will fail for users with insufficient
privilege to profile the kernel.
