uh.. sorry, was composed in email client. seems the correct way to do it is
+#if defined CONFIG_DEBUG_PAGE_REF && defined CONFIG_TRACEPOINTS
#include <linux/tracepoint-defs.h>
#define page_ref_tracepoint_active(t) static_key_false(&(t).key)
extern struct tracepoint __tracepoint_page_ref_set;
...
extern void __page_ref_set(struct page *page, int v);
...
#else
#define page_ref_tracepoint_active(t) false
static inline void __page_ref_set(struct page *page, int v)
{
}
...
#endif
or add a dependency of PAGE_REF on CONFIG_TRACEPOINTS in Kconfig.
