From mboxrd@z Thu Jan 1 00:00:00 1970 From: David Arcari Subject: [PATCH] tools/power turbostat: return the exit status of a command Date: Tue, 12 Feb 2019 09:34:39 -0500 Message-ID: <1549982079-23516-1-git-send-email-darcari@redhat.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: linux-pm@vger.kernel.org Cc: David Arcari , Len Brown , Jirka Hladky , linux-kernel@vger.kernel.org List-Id: linux-pm@vger.kernel.org turbostat failed to return a non-zero exit status even though the supplied command (turbostat ) failed. Currently when turbostat forks a command it returns zero instead of the actual exit status of the command. Modify the code to return the exit status.
