Next, we compared the source code of the Linux Kernel 4.5.2 to the LLVM+Clang system, version 3.8.0. These two projects are each a large program that are not known to actively share code. There may be some very minimal similarity simply due to chance, but something much lower than the 3.68% found between Linux and FreeBSD's kernel.
Indeed, when the same test is run to compare Linux to the LLVM+Clang system, the "ratio of similarity" was 0.075%.
With the baseline established, we now begin relevant comparisons. First, we compare the Linux kernel version 2.6.34 to the sources released by VMware in their (partial) source release. The "ratio of similarity" between Linux 2.6.34 and VMware's partial source release is 20.72%. There is little question that much of VMware's kernel has come from Linux.

The following describes a methodology to show Hellwig's contributions to Linux, and how they compare to code found in VMware ESXi 5.5.
