Indeed, msr.h is an issue. So having tracepoint_enabled() in include/linux/tracepoints-defs.h and going through a function would make sense for this kind of core use-case I guess. I tried including tracepoint.h from include/linux/page_ref.h and did not notice any compile issue. Am I missing something to trigger an issue related to that scenario ?
