From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnaldo Carvalho de Melo Subject: [PATCH 11/22] perf tests record: Allow for 'sleep' being 'coreutils' Date: Fri, 30 Nov 2018 15:26:41 -0300 Message-ID: <20181130182652.23620-12-acme@kernel.org> References: <20181130182652.23620-1-acme@kernel.org> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: In-Reply-To: <20181130182652.23620-1-acme@kernel.org> Sender: linux-kernel-owner@vger.kernel.org To: Ingo Molnar Cc: Clark Williams , linux-kernel@vger.kernel.org, linux-perf-users@vger.kernel.org, Adrian Hunter , Jiri Olsa , Arnaldo Carvalho de Melo List-Id: linux-perf-users.vger.kernel.org From: Adrian Hunter If the 'sleep' command is provided by coreutils, then the "PERF_RECORD_* events & perf_sample fields" test will fail because the MMAP name is 'coreutils' not 'sleep', and there is an extra COMM event. Fix the test to detect that case.
