<h3>修改内核源代码<a class="headerlink" href="#modify-kernel-source-code" title="永久链接至标题"></a></h3>
<p>对内核代码的更改通过补丁文件应用。补丁文件是格式化的 git 提交，可以应用于主源代码。</p>
<p>您需要获得源代码的副本，进行修改，生成补丁文件，然后将它们添加到 RPM SPEC 文件中，以便在内核构建期间包含在内。</p>
<p>如果有大量补丁或工作流程十分复杂，可考虑在 Git 之外使用 <a class="reference external" href="http://savannah.nongnu.org/projects/quilt">Quilt</a> 之类补丁管理工具。</p>
