From: "Steven Rostedt (Red Hat)" <[email protected]> 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.
