How do I know what linux kernel version does a distribution use?
<p>When I run </p>

<pre><code>uname -r
</code></pre>

<p>I get 3.2.0-4-686-pae on my Debian7 and 4.4.26-gentoo on my Gentoo.</p>

<p>But what I can't find anywhere is what Linux kernel source versions do these distributions use. If I understand right all distributions take the kernel source code from here <a href="https://www.kernel.org" rel="nofollow noreferrer">https://www.kernel.org</a>. So how can I find out what Linux kernel versions from the site do use 4.4.26-gentoo or 3.2.0-4-686-pae, for example?</p>
