Did you know how the kernel development work. I know it very hard to make the kernel working. Most are developers working together. Not like Carnonical aka Ubuntu… They take but never return said by Greg Kroah-Hartman. This one already explained by him on my previous post
Here

You all can view the picture how the kernel development process.

Watch and hear about the kernel development. How the kernel come out.. how about the time line…who is the contributor with the Greg Kroah-Hartman. “How about the Ubuntu involved in kenel..They take but never return..Hahaha..dont be selfish “

Who is this guy?

Greg Kroah-Hartman is a Linux kernel hacker. He is the current Linux kernel maintainer for the USB, driver core, debugfs, kref, kobject, and the sysfs kernel subsystems. He is also the maintainer of the linux-hotplug and created the udev projects. Additionally, he helps to maintain the Gentoo Linux packages for these programs, and helps with the kernel package. He works for Novell in the SUSE Labs division. He is currently working full time on the Linux Driver Project.[1]

He is a co-author of “Linux Device Drivers, 3rd Edition”[2] and author of “Linux Kernel in a Nutshell”,[3] and used to be a contributing editor for Linux Journal. He also contributes articles to LWN.net, the news computing site.

Kroah-Hartman frequently helps in the documentation of the kernel and driver development through talks[4][5] and tutorials.[6][7] In 2006, he released a CD image of material to introduce a programmer to working on Linux device driver development.[8]
