Subject: [PATCH AUTOSEL 4.4 11/21] tools/power turbostat: return the exit status of a command
Date: Fri, 29 Mar 2019 20:56:39 -0400 [thread overview]
Message-ID: <20190330005649.28475-11-sashal@kernel.org> (raw)
In-Reply-To: <20190330005649.28475-1-sashal@kernel.org>
From: David Arcari <darcari@redhat.com>
[ Upstream commit 2a95496634a017c19641f26f00907af75b962f01 ]
turbostat failed to return a non-zero exit status even though the
supplied command (turbostat <command>) 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.
