Every tracing file must have its own TRACE_SYSTEM defined. The iwlwifi tracepoint header broke this and added in the middle of the file: #undef TRACE_SYSTEM #define TRACE_SYSTEM iwlwifi_io #undef TRACE_SYSTEM #define TRACE_SYSTEM iwlwifi_ucode #undef TRACE_SYSTEM #define TRACE_SYSTEM iwlwifi_msg #undef TRACE_SYSTEM #define TRACE_SYSTEM iwlwifi_data #undef TRACE_SYSTEM #define TRACE_SYSTEM iwlwifi Unfortunately, this broke new code in the ftrace infrastructure. Moving each of these TRACE_SYSTEMs into their own trace file with just one TRACE_SYSTEM per file fixes the issue.
