kprobes

hi,

i saw this on lwn.net:
IBM developerWorks [0] shows how to use Kprobes to debug the Linux kernel. 
"The benefits of using Kprobes are many. printk's can be inserted without 
rebuilding and rebooting the kernel. Processor registers can be logged and 
even modified for debugging -- without disruption to the system. Similarly, 
Linux kernel data structures can also be logged and even modified 
non-disruptively as well. You can even debug race conditions on SMP systems 
with Kprobes -- and save yourself the trouble of all that rebuilding and 
rebooting. You'll find kernel debugging is faster and easier than ever."


maybe that could be _real_ useful for the vserver project ? :-)
