From c5d9104281b9a9d8c91d3937c08b318da7ef9ae7 Mon Sep 17 00:00:00 2001 From: David Arcari Date: Tue, 12 Feb 2019 09:34:39 -0500 Subject: [PATCH] tools/power turbostat: return the exit status of a command [ Upstream commit 2a95496634a017c19641f26f00907af75b962f01 ] 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.
