Subject: Re: Ftracing in linux 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
