From 3c18a9be7c9d4f53239795282c5d927f73f534b3 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (VMware)" Date: Thu, 20 Feb 2020 16:29:50 -0500 Subject: tracing: Have synthetic event test use raw_smp_processor_id() The test code that tests synthetic event creation pushes in as one of its test fields the current CPU using "smp_processor_id()". As this is just something to see if the value is correctly passed in, and the actual CPU used does not matter, use raw_smp_processor_id(), otherwise with debug preemption enabled, a warning happens as the smp_processor_id() is called without preemption enabled.
