He is still “the ultimate authority on what new code is incorporated in the standard Linux kernel,” according to the Linux Foundation, the non-profit consortium that promotes Linux and supports its development. The Linux Foundation reports that 7,800 people from almost 800 different companies have contributed to the kernel since 2005.
