The traced result is very complete and intact. But it seems too large to grasp the interested content. For example, one may only have interest in functions calling in usbcore.ko, but he must trace all the functions calling in the kernel, so the tracing result is too large to use it. Could you add the support of tracing functions in one module only to ftrace?
