title: kernel source code location in linux
body: <p>I am working in <code>Windows</code> and running <code>fedora</code> through VMware.</p>
  
  <p>By default, the kernel source tree should be in <code>usr/src/</code> directory. Instead I could find only an empty directory called kernels. The actual source code is missing there.</p>
  
  <p>When browsing I thought it might be in other directories like <code>/boot</code>. But I couldn't find source tree there as well.</p>
  
  <p>I need to modify system call tables for which I should be able to access those source codes.</p>
