Youtube Summary
Google Tech Talks
June, 5 2008


The Linux Kernel, who is developing it, how they are doing it,
and why you should care.

This talk describes the rate of development for the Linux
kernel, and how the development model is set up to handle such a
large and diverse developer population and huge rate of change.
It will detail who is doing the work, and what companies, if
any, are sponsering it. Finally, it will go into why companies
like Google, and any other that uses or depends on Linux, should
care about this development. Lots of numbers and pretty graphs
will be shown to keep the audience awake.

Speaker: Greg Kroah Hartman
Greg Kroah-Hartman is a Linux kernel maintainer for the USB,
driver core, sysfs, and debugfs portions of the kernel as well
as being one half of the -stable kernel release team. He
currently works for Novell as a Fellow doing various kernel
related things and has written a few books from O'Reilly about
Linux development in the past.

Shameless Plug:

I was very fortunate to have a conversation with him a few years ago. We talked a bit about his journey and a bit about his hacks, his setup, and of course a lot about Linux:

For reference for HN users who don't know who this is:

> Greg Kroah-Hartman is a major Linux kernel developer. As of April 2013 he is the Linux kernel maintainer for the -stable branch, the staging subsystem, USB, driver core, debugfs, kref, kobject, and the sysfs kernel subsystems, Userspace I/O (with Hans J. Koch), and TTY layer.

From Wikipedia:

He is the guy that corporate guys feel more “manageable”than Linus.

Linus has been losing control on Linux directions long time ago.

> Linus has been losing control on Linux directions long time ago.

I'm interested :)

Corporate guys "manage me"? Have you talked to any corporate guys who have actually tried that and discussed the results with them? :)
I think that two fiascos that you've been a part of, kdbus [1][2] and UMN [3], have conditioned some people to view you in a certain light.




What is probably meant is "find easier to deal with" (hence the quotes around "manageable"). I'm only guessing, though - but in any event, let's not forget that not everyone around here is a native speaker of English! I can relate to the fact that it's sometimes difficult to express exactly what you have in mind.
I think it's fair to say he's the number two guy in the kernel. Is he younger than Linus? I could see him running the show when Linus has enough and calls it a day.
From what I understood, when Linus took his break a few years back, this is exactly what happened.
I can't edit any more, but I've looked around, and this clearly isn't true. For some good details on the size of the Linux project, check out the beginning of this talk by Greg Kroah-Hartmann, one of the chief kernel devs; it's from 2008, but things have only moved faster on the kernel:
Here is a YouTube (Google Tech Talks) video on how the Linux kernel is developed:
