Canonical ranked #79 in Linux kernel contribution

An interesting keynote in Linux Plumber Conference 2008 by Greg Kroah-Hartman about Canonical's (the company behind Ubuntu) contribution in Linux kernel. Here is the numbers :

• Canonical has had 100 patches in the Linux kernel,
• which is 0.1% of all of the kernel development in the past 3 years, from the 2.6.15 kernel to 2.6.27-rc6.
• ranked 79th of all companies doing kernel development
• ranked 195th as an individual contributor to the kernel

It may be a surprise to everyone that a leading Linux distribution provider Cannoical did not involve much in kernel development. To me, it is not a surprise, and I fully understand this as a consequence. Debian had long been complaining Ubuntu did not contribute back to Debian, although Ubuntu takes everything from Debian, and create its own distribution by their own. Ubuntu has the same ecosystem as in Voyage Linux as well. I build Voyage Linux based on Debian packages and customize the kernel using Debian's and patches from other sources (e.g. openwrt, layer 7, -mm patches). Voyage Linux never had contributed a single line of code since all of the work in Voyage Linux is integration - incorporate open source software into a workable product.
