Subject: [PATCH 28/77] perf stat: Move 'no_inherit' to 'struct perf_stat_config'
Date:   Wed,  5 Sep 2018 19:03:51 -0300
Message-Id: <20180905220440.20256-29-acme@kernel.org>
In-Reply-To: <20180905220440.20256-1-acme@kernel.org>
References: <20180905220440.20256-1-acme@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Jiri Olsa <jolsa@kernel.org>

Move the static 'no_inherit' variable to 'struct perf_stat_config', so
it can be passed around and used outside the 'perf stat' command.
