Linus Torvalds server where the kernel was first hosted for download, named Torvalds's directory "linux". As of 2006, approximately two percent of the Linux kernel was written by Torvalds himself. Because thousands have contributed to the Linux kernel, this percentage is one of the largest contributions to it. However, he stated in 2012 that his own personal contribution is now mostly merging code written by others, with little programming. Torvalds retains the highest authority to decide which new code is incorporated into the standard Linux kernel. Torvalds holds the "Linux" trademark and monitors the use of it, chiefly through the Linux Mark
Hybrid kernel Hybrid kernel A hybrid kernel is an operating system kernel architecture that attempts to combine aspects and benefits of microkernel and monolithic kernel architectures used in computer operating systems. The traditional kernel categories are monolithic kernels and microkernels (with nanokernels and exokernels seen as more extreme versions of microkernels). The "hybrid" category is controversial, due to the similarity of hybrid kernels and ordinary monolithic kernels; the term has been dismissed by Linus Torvalds as simple marketing. The idea behind a hybrid kernel is to have a kernel structure similar to that of a microkernel, but to implement that structure in
