Subject: [PATCH 1/5] perf tests: Run ctags/cscope make tests only with needed binaries
Date: Mon, 22 Jul 2013 14:43:30 +0200
Message-Id: <1374497014-2817-2-git-send-email-jolsa@redhat.com>
In-Reply-To: <1374497014-2817-1-git-send-email-jolsa@redhat.com>
References: <1374497014-2817-1-git-send-email-jolsa@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

Running tags and cscope make tests only if the 'ctags'
and 'cscope' binaries are installed, so we don't have
false alarm test failures.
