The category “Unknown” is responsible for 12,060 changes to the Linux kernel, or 6.4 percent of the total work. According to the Linux Foundation, “There are a number of developers for whom we were unable to determine a corporate affiliation. … With few exceptions, all of the people in this category have contributed 10 or fewer changes to the kernel over the past three years, yet the large number of these developers causes their total contribution to be quite high.”
