And off again! Another TGV, this time a seven-hour run from Paris to Barcelona. Managed to secure myself a first-class seat on the top floor for this, so should be a fantastic view the whole way.

Also, the French trains are *long*! Which is always great to discover when arriving at the platform a few minutes before departure and then having to walk the whole length of the train to get to the furthest carriage... 😅

Made the connection! Looks like the first day of travel will be a success, and I'll be in Paris in an hour or so! 🥳

And oh boy, I don't think I'll ever get tired of the French TGVs! Weeeh! 😃

Second day, Hamburg-Paris via Mannheim. First train only slightly delayed thus far, so my 11-minute connection time is now down to 7 minutes according to the DB projection. Should be fine, right? 😅

Otherwise quite comfortable on the ICE, there's even WiFi that sometimes works!

Starting out on my three-day trip by train from Denmark to Portugal. Off to a great start with the Copenhagen-Hamburg train being half an hour late before I even got on it, and also missing a carriage so the remaining ones are packed to the brim. Yay, adventure! 😂 #trains

You're welcome! Although this is mostly courtesy of the nice people at Karlstad university who handle the whole thing 😊 Glad you like it!

Thanks! Glad you enjoyed it! I think the flag might work, but I was using the .ko shipped by my distro, which does not have the debug information required for --source.

First blog post (after restarting blogging) is out!

In which I explore the use of kprobes in the middle of a function and reveal that I am not, in fact, very good at reading assembly code... 😅

I know what you mean! Skipping plumbers myself this year for this reason. I think you could probably present remotely? 🤔

Bugbot status update: it's now able to monitor lore lists and start tracking threads as bugs based on an arbitrary query. E.g. you can mention "bugbot engage" in a thread and the entire thread will be converted to a bugzilla bug (if the email of the person issuing this command matches a bugzilla account with "editbugs" group membership). Any subsequent messages in the thread will be automatically added to the bug as new comments. Any comments posted on the bug via bugzilla interface will be sent to original recipients.

Now working on the other direction -- bugs added in bugzilla will be converted to mailing list threads and sent to proper maintainers (based on certain conditions, e.g. a "bugbot" flag needs to be set to "on" and the cf_subsystem custom field needs to match the corresponding MAINTAINERS entry). Should be done tomorrow, at which point I'll be looking for early testers. :)

Who ever said cat herding was a waste of time? 😆 how else are we going to get all the proud roaming felines to pay attention to what's important? 😅

Nah, but your general point is still valid - test with upstream, folks! 🙂

In this particular case I think that all Canonical did with their kernel was "have a working build environment", though... :/

(He's talking about the libxdp dispatcher, which works fine on upstream kernels. I know that because I wrote it 😅)

@ljs @LWN Yup, agreed! I read (almost) everything LWN puts out and it's consistently well-written and informative. Really impressive!
