I received an email from my test suite that it failed while I was on the plane waiting for everyone to board. I ssh'd into my server with the Connect app, found it was a configuration issue, fixed the configuration and restarted the tests, before they closed the aircraft door!

-Werror is great, until you need to debug an older kernel 😛

This meme perfectly describes pretty much every interaction between Linus Torvalds and myself!

I think this is the first time I ever used the quadratic equation for a real purpose since college! 🤔

Not every day you can say you were complemented by Linus Torvalds saying you had an “interesting idea”. Always look for those silver linings!

Fixing up a messed up Debian upgrade where I needed to reinstall, I had to hit “Select this only if you know what you are doing”. I don’t know what I’m doing, but I had to hit it to do what I needed to get done 😛

Another useful email to the Linux Plumbers mailing list!

Kernel Recipes (which is always held in Paris) is thinking of changing their logo.

Last night at the real-time celebration, Thomas Gleixner handed Linus Torvalds his official pull request of the real-time patch on paper "wrapped in gold with a ribbon around it''

THIS IS IT!!!

The last hurdle for PREEMPT_RT being merged into mainline has just removed by this pull request. Leaving the door open for PREEMPT_RT to be added to 6.12!

With my new persistent memory mapped ring buffer, were I can retrieve the tracing buffer from the previous boot that crashed, I was able to debug a recent issue. To do this, I added code to allow trace_printk() to be directed to the persistent ring buffer, along with enabling the printk console trace event (writes all printk()s to the tracing ring buffer), I was able to get the perfect idea of what was happening that lead up to the crash!

Linus Torvalds: And for everybody else as a "It's happening" heads-up.

Linux Plumbers 2024 has accepted 9 Microconferences! But we had 26 submissions for 18 slots! What to do with that? Read about it here: https://lpc.events/blog/current/index.php/2024/05/03/awesome-amount-of-microconference-submissions/

Just posted a proof of concept that allows you to read a trace after a reboot, including a kernel crash!
