Subject: [PATCH AUTOSEL 3.18 09/15] tools/power turbostat: return the exit status of a command
Date: Fri, 29 Mar 2019 20:57:24 -0400	[thread overview]
Message-ID: <20190330005730.28777-9-sashal@kernel.org> (raw)
In-Reply-To: <20190330005730.28777-1-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.
