So who are the top contributors to the Linux Kernel?

Greg Kroah-Hartman of SuSE Labs along with Jon Corbet of LWN.net and the Linux Foundation just published a very informative state of the union of the Linux Kernel development world.

The kernel is one of the largest collaborative software projects on the planet. According to the report, over 3700 individual developers from over 200 different companies have contributed to the kernel since 2005. That's amazing!

I found a couple of very interesting facts in this report - the top 30 contributors and the top 30 organizations sponsoring kernel development.

The top 30 contributors include:
