Ftracing in kernel

Hi folks, I've configured my kernel(2.6.35) to support ftrace*. Everything seems to be ok. After I mounted the debugfs folder I can find all tracing stuffs there. The problem is not of all functions on my module seems to be listed in the funtions supported for tracing. In the file *available_filter_functions *that suppose to list all functions traced, only show 4 or 5 functions of my module. Does anyone knows why some functions are not listed? Regards, Erlon *CONFIG_FUNCTION_TRACER CONFIG_FUNCTION_GRAPH_TRACER CONFIG_STACK_TRACER CONFIG_DYNAMIC_FTRACE
