Collecting debugging information from the Linux™ kernel using printk is a well-known method — and with Kprobes, it can be done without the need to constantly reboot and rebuild the kernel. Kprobes, in combination with 2.6 kernels, provides a lightweight, non-disruptive, and powerful mechanism to insert printk’s dynamically. Logging debug info such as the kernel stack trace, kernel data structures, and registers has never been so easy!

I don’t mean to be off-topic, but why the TM trademark symbol in the writeup?
Because it was submitted that way by an IBM employee (anonymous, but we know that IBM employees are submitting the developerWorks articles to all news sites).
I usually strip the TM and OR signs out, but sometimes I don’t see them in time (like in this case). It’s not a big deal, I don’t really care.
ibm developerworks is an excellent source of info and tutorials to new technologies. this is another example – thanks to osnews for pointing to them, and thanks to ibm for hosting them. “i didn’t know you could do that with linux” – it is a very useful mechanism. shows how much linux has become a very mature OS suited to very professional use.
Not sure how you feel about it (well can’t imagine you are too opposed since you posted it) – but I think it’s a great idea for them to submit them other news sites. The articles on Developer Works are usually very interesting and well-written. I have seen a few stinkers, but, overall it’s a good source for information.
Why remove them, Linux is actually Trademarked after all.

most of the enforcement is done by Linux international. its just there to prevent abuse of the word.

Nope. He has applied for the trademark, so that nobody else could apply for it.
Why doesn’t everyone else write it as Linux™? I’m guessing the millions of people who mistype are actually diluting the brand, much like Xerox™ and Kleenex™. Before you know it, Linux will be a generic term for an operating system, and Linus Torvaldses will lose his trademark.
