Those functions are only detected in available_filter_functions if the module is inserted. If the module i already inserted, I cant trace the init function anymore since the init has already finished. What is the solution with ftrace? Or should I resort to some other tracing tool ? -- Thanks and Regards, Aurabindo J _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
