Subject: [PATCH 13/14] perf stat: Move enable_on_exec setup under earlier code
Date: Mon,  7 Dec 2015 19:17:18 -0300	[thread overview]
Message-ID: <1449526639-3667-14-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1449526639-3667-1-git-send-email-acme@kernel.org>

From: Jiri Olsa <jolsa@kernel.org>

It's more readable this way and we can save one
perf_evsel__is_group_leader condition in current code.
