Are you suggesting moving the example code into kernel? Or complaining

That's not a good excuse. In fact it's a very bad one.
Especially example code needs to b

Hi David,
Interesting work, but I think we could still enhance it. The interesting
things you bring is the trace control though debugfs files, which is
clear and simple. (I did it on top of netlink in LTTng, but I don't
really care about the mechanism, as long as we have the same
flexibility).

Hi David.
A random comment to the code.
Several of the struct file_operations are not declared static as
they should be.
Btw. it looks good from a coding style point-of-view.
About the name what about ktrace??

Hi David.
A random comment to the code.
Several of the struct file_operations are not declared static as
they should be.
Btw. it looks good from a coding style point-of-view.
