Subject: [PATCH V3 1/3] perf tool: Fix perf diff symble sort issue
Date: Mon, 17 Nov 2014 09:52:17 -0500 [thread overview]
Message-ID: <1416235939-29565-2-git-send-email-kan.liang@intel.com> (raw)
In-Reply-To: <1416235939-29565-1-git-send-email-kan.liang@intel.com>
From: Kan Liang <kan.liang@intel.com>
This patch fixes a bug for perf diff.
Without mmap2, perf diff fails to find the symbol name. The default
symbol sort key doesn't work well.
