<p>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 written in the C programming language, but they are not known to actively share code. We would expect some very minimal similarity simply due to chance, but something much lower than the 3.68% found between Linux and FreeBSD's kernel.</p> <p>Next, we compared the source code of the Linux Kernel 4.5.2 to the LLVM+Clang system, version 3.8.0.

<p>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 &quot;ratio of similarity&quot; 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.</p> <p>With the baseline established, we now begin relevant comparisons.
