1. HOWTO - apply a Linux kernel patch to the stable tree

2 years ago

This is a screencast of the steps involved in applying a patch to the Linux -stable kernel series.

It shows the scripts and tools used (quilt, git, mutt, and others) and how it all works together.

:)) Thanks a lot Greg, yes it was fun!!! Now is it possible to have that for every kernel maintainer ;) event from Linus :)

This was fun and very instructive and like you said it lacks sound, maybe a jamendo tune next time ;) ?

It's nicer if you can just pick your own music to play while watching it, that way you know you will enjoy it :)

Very informative.

On a sidenote, I liked your bash prompt coloring scheme ($PS1) , can you give the bashrc command that you have for it ?

Hi. Did you try stgit? It adds all the quilty stuff on top of git, so you don't have to import/export the patches into quilt just to able to toss them around more freely.

Or is there an other reason for using quilt?
Greg KH 2 years ago

Last I looked stgit isn't as fast as quilt, has that changed?

Also, it is easier to share stuff as a quilt tree, than a stgit tree, although, again, that might have changed since I last looked.

And, stgit also used to not handle patches in mbox format very easily, again, that might have changed.

Either way, I would have to import the patches into a stgit tree, to handle them this way, right?

Not really. You just create a branch in your normal git tree, and run 'stg init' on it. Then you run 'stg pick' on the interesting commits from the upstream branch. As i understand it, patches need already be upstream to get into the stable tree, right?

From the git's point of view, the stgit-ed branch looks exactly like any other one, and the stgit patches in it are in fact git commits. So after you are done, you can push it to a public git repo, so no import/export is ever needed.

Not sure about if it got faster, but I've never had any problems with its speed, but then, I've never worked on queues longer than a few tens commits.

Thank you very much for the video. Always wanted to see how you guys (I mean top-level lieutenants) operate... It's really impressive. The only thing is missing: Could you please share those 'little bash scripts' (probably upload them to kernel.org in your personal directory there)? Just for completeness, of course if you don't mind and have a spare minute...

The scripts are all in the stable-queue git tree on git.kernel.org that I use for applying patches and sending email notifications.

Other scripts that I use for applying patches for development stuff are already in my gregkh directory on kernel.org.

Hey that was really informative. Some little questions:

How does ketchup helps in this process?
I'm not familiar at all with git's mbox facilities but isn't there a way to automatically generate patches from stable@ list using git?

Thanks a lot!

Very interesting! Thanks alot for this video. I didn't know quilt which is very cool until I saw this video.

Is there a special reason you use mutt or for no reason?

Regards,
Lukas
