What goes into a Linux kernel patch?

LWN.net has an interesting look today at who had a crack at (and who had the biggest crack at) patching up the Linux kernel for version 2.6.20.

If you’ll remember, I managed to get an article up on SearchEnterpriseLinux.com about this the day after the Super Bowl (I had just barely finished shredding my Bears jersey when my fingers hit the keyboard). KVM, or Kernel-based Virtual Machine, was the talk of the town then, but today we get to see which developers had the biggest impact on the latest stable kernel release.

This study looked at the stream of patches that changed the 2.6.19 kernel into the current 2.6.20 release. There were, as it turns out 4983 non-merge changesets in this release, contributed by 741 different developers.

But even more interesting, I think, is looking at who paid who to get things put into the kernel. IBM, Red Hat and Novell top a few lists, but so did a few surprises like Sony. It’s definitely worth a look when you get the chance.
