LOL redhat has under 1000 world wide employees can you please provide me with proof that more than 20% of their employees are involved in kernel development? I speak as someone who has a business relationship with the company (I buy their stuff) and as someone who uses it personally so pretty please tell me where you get this knowledge of the number of Redhat employees doing kernel hacking... Where is your source for the number of redhat employees working on Kernel modifications?
As testament to Red Hat's active participation in the upstream Linux kernel community, through the course of 2.6 development more patches were accepted from Red Hat kernel developers than from any other company. During the past year, more than 4,100 patches from Red Hat employees were integrated into the upstream 2.6 kernel.
