In a recent discussion on the Linux Kernel mailing list, it was asked "which companies are helping develop the kernel?" One response pointed out that that a recent article on lwn.net summarized this information nicely. Others pointed to a paper maintained by Greg KH, who responded:
"Yeah, but my paper didn't really track companies very well. The lwn.net article is the best, and below is my version of who did things in 2.6.23. Note, the lack of a company is not an indicator that they did nothing, just that I could not easily determine someone worked for them. I'll try to send out my 'who are you working for' emails in a week or so to see if I can further categorize the 'unknowns'."
According to Greg's email, organizations that contributed more than 100 changesets to the recently released 2.6.23 kernel included: Red Hat with 827 changesets (11.7%), IBM with 557 changesets (7.9%), the Linux Foundation with 528 changesets (7.5%), Novell with 449 changesets (6.3%), Intel with 242 changesets (3.4%), Oracle with 158 changesets (2.2%), MIPS Technologies with 143 changesets (2%), Nokia with 133 changesets (1.9%), and NetApp with 119 changesets (1.7%). Greg noted that there were a total of 7,075 changesets from 992 developers working for 126 different employers. 843 of the changesets (11.9%) were contributed by individuals reporting no sponsor for their work.

Subject: Which companies are helping developing the kernel
Date: Oct 14, 6:06 pm 2007
Hello,
I posted this question at comp.linux.misc and where told this would be a better place therefore.
I would like to do a internship in the field of the Linux kernel.
Can someone tell me where to find a list of companies (don't matter in which
country) that employ kernel developers?
Stefan

I think Greg wrote a paper on this subject, so I've added him to CC in case he
has the link handy.

Yeah, but my paper didn't really track companies very well. The lwn.net
article is the best, and below is my version of who did things in
2.6.23. Note, the lack of a company is not an indicator that they did
nothing, just that I could not easily determine someone worked for them.
I'll try to send out my "who are you working for" emails in a week or so
to see if I can further categorize the "unknowns".
thanks,
