Message-Id: <1411452737-28188-1-git-send-email-treeze.taeung@gmail.com>
Date: Tue, 23 Sep 2014 15:12:17 +0900
From: taeung <treeze.taeung@...il.com>
To: Arnaldo Carvalho de Melo <acme@...nel.org>

Subject: [PATCH] modify error code when perf_session__new() fail.
Because perf_session__new() could fail
for more reasons than just ENOMEM,
I modified error code(ENOMEM or EINVAL)
into -1.
