From 97f8827a8c7963756ae7d3ee898675b4667eca73 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Mon, 23 May 2016 10:04:46 -0400 Subject: [PATCH] ftracetest: Use proper logic to find process PID Half of the test in instance-event.tc was updated to use $! to find the PID of the previous background process that was launched, but the second part of the test still used the parsing of "jobs", which does not work on all shells like $! does.
