Can haz kernel patches?

As it’s only a couple of weeks till another Linux.conf.au is underway, I thought I better post this draft from the last one! This year LCA is in Wellington, New Zealand, sadly I didn’t get my act together enough to make a proper holiday of it. I’m definitely looking forward to catching up with all the cool hackers at the conference.

One of the best talks I went to Linux.conf.au last year was the Ksplice talk. This is a wonderful tool which allows people to develop “hot patches” so that you never need to reboot again. The developers have done some very cool work which means for 88% of patches a hot fix can be generated automatically. The presenter was a really great speaker too, during the talk he explains some advanced concepts (like hot to fix-up memory structures) I was able to easily understand it all. I can’t watch until I never have to reboot my Linux machines again!

I also attended Rusty‘s tutorial on hacking lguest. Two years ago I submitted a very important patch to lguest which is now included in the kernel. This year I didn’t get as far as I had wanted mostly because I had not gotten enough sleep the night before. I did however submit one patch which was accepted. I guess that makes me a kernel hacker :).

Sadly, Rusty won’t be running another lguest tutorial this year, so it’s unlikely I’ll submit a third patch.
