All of this stuff is no-op and could just as easily be removed
completely as GASKET_KERNEL_TRACE_SUPPORT is not #defined anywhere.

Is the actual trace #include file supposed to be available somewhere?

#ifdef GASKET_KERNEL_TRACE_SUPPORT
#define CREATE_TRACE_POINTS
#include <trace/events/gasket_ioctl.h>
#else
#define trace_gasket_ioctl_entry(x, ...)
#define trace_gasket_ioctl_exit(x)
#define trace_gasket_ioctl_integer_data(x)
#define trace_gasket_ioctl_eventfd_data(x, ...)
#define trace_gasket_ioctl_page_table_data(x, ...)
#define trace_gasket_ioctl_config_coherent_allocator(x, ...)
#endif

trace file not found...
