Speaker selfie at #kr2026

@KernelRecipes And my obligatory selfie

Anyone else in town for Kernel Recipes?

@almalinux Can you have Andrew Lukoshko email me (rostedt@goodmis.org) with his email if he wants to attend Linux Plumbers. He’s next on the wait-list but only put in a user name for his email (no @email.org part). If I don’t get a response by tomorrow, Friday Sept 18th, I’ll give the spot to the next person on the wait-list.

I would have normally have skipped him, but he has high enough profile to make an effort.

@vbabka @oleksandr @poni @lkundrak @ozzelot Note, ftrace was not the cause of the bug. The bug was that NVRAM happened to be left writable. Ftrace was simply the reproducer!

@vbabka @oleksandr @lkundrak @poni @ozzelot Who me?

Does that tree at least work for you? Maybe we can convince somebody
who is a better maintainer than I clearly have ever been to make my
messy branch be something actually palatable...

            Linus

Not a quote I would expect to see from him! (Yes, this is totally out of context)

Linux Plumbers Conference 2026 is now SOLD OUT!

But you can still attend if you add yourself to the wait-list and a spot opens up for you.

On this day 18 years ago, ftrace entered mainline! https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e18425a0abc

If you use trace_printk() for debugging and do not want to now have to add #include <linux/trace_printk.h> to every file you use it in, please reply to Linus and tell him.

@monsieuricon I’ve always wondered if the hyphenated names make using your “mother’s maiden name” useless as a security word for banks?

All Microconferences have been accepted for Linux Plumbers. If you have something to discuss, go ahead and submit a topic to your favorite MC!

On a related note. I finally switched my .emacs file to use xref-find-definitions instead of the find-tags which has been obsolete since 2016!

I believe I win the Procastination Award for the time between sending a v2 after a v1 patch. I had a patch to fix make TAGS to not include structure members and posted it to the mailing list. I received reviews to make it better, but things came up and I never got around to sending a v2. I left the conversation in my INBOX and every time I saw it, I would say to myself “Oh, I’ll have to finish that later”. In the mean time I would just manually apply the patch via quilt push whenever I did a make TAGS. I finally got around to sending the v2. The v1 was sent out in 2013!!! It’s only been 13 years since I wrote v1 😛

@ljs @ptesarik That code also fixed doing a full stack trace dump of every task (sysrq-t) when an NMI discovered a lock up. Stack traces can fault, which would re-enable NMIs, and because every task's stack trace is being printed to the console in NMI context, another NMI would trigger, corrupting the stack of the first NMI and crash the system before all the stack traces could be printed. This was annoying when trying to debug hard lockups.

@ljs @ptesarik I missed the post and only saw the replies. Could you email me the original if you still have it. I'm curious to what you said. Don't worry, I won't hold it against you 😉
