Or do what some other drivers do, which is to make a separate file to hold the creation of the tracepoints, and have it included in whatever needs it. Export them if there's more than one module. drivers/media/v4l2-core/v4l2-trace.c: #define CREATE_TRACE_POINTS #include "v4l2-trace.h" See fs/xfs/xfs_trace.c as an example. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
