 I propose to replace 'Pr_debug', 'Dev_debug', and 'DEBUGP' with 
kernel markers. SystemTap is used for the output of the log.  

 I propose to make it to the function to output only specified 
kernel markers as a log and the function in a word like LTTng of
a simple version by using the framework and kernel markers of 
ftrace if the log is output by using debugfs. 

Thank you,
