From bd41202214f8e89db3a64f8031d29d081f268190 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Wed, 1 Apr 2015 14:19:06 -0400 Subject: [PATCH] tracing: Add TRACE_SYSTEM_VAR to kvm-s390 New code will require TRACE_SYSTEM to be a valid C variable name, but some tracepoints have TRACE_SYSTEM with '-' and not '_', so it can not be used. Instead, add a TRACE_SYSTEM_VAR that can give the tracing infrastructure a unique name for the trace system.
