It appears there's a bug in the TRACE_EVENT_ENUM define that doesn't translate the TRACE_SYSTEM properly and it created the same variable used for both kmem.h and mmflags.h and the build failed. So v2 will also include a fix to TRACE_DEFINE_ENUM(). -- Steve > + > TRACE_EVENT(kmem_cache_alloc, > > TP_PROTO(unsigned long call_site, > diff --git a/include/trace/events/mmflags.h b/include/trace/events/mmflags.h > index bb8a59c6caa2..522bbe3a5fe1 100644 > --- a/include/trace/events/mmflags.h > +++ b/include/trace/events/mmflags.h > @@ -15,6 +15,8 @@ > > #define gfpflag_string(flag) {(__force unsigned long)flag, #flag} > > +TRACE_DEFINE_GFP_FLAGS > + > #define __def_gfpflag_names \ > gfpflag_string(GFP_TRANSHUGE), \ > gfpflag_string(GFP_TRANSHUGE_LIGHT), \ > --
