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,
