title: The easiest way to extend Linux version in Yocto
body: <p>I'm trying to extend Linux version in my project on a tag from git repository. I manged to pass tag value to Linux-*.bb and looking for the best solution to add it to kernel version so I can see it in /etc/kernel-version file and as an output after typing <code>"uname -r" e.g: 3..11.67-my-tag</code>.</p>
  
  <p>I know that there is something like LINUX_KERNEL_EXTENSION but I didn't mange to make it working.</p>
  
  <p>What is the easiest way to do it and how can I test it without flashing my board?</p>
  
  <p>Thanks,</p>
