<p>如果你在第一章练习题中已经借助 <code class="docutils literal notranslate"><span class="pre">log</span></code> crate 实现了日志功能，那么你可以直接在 <code class="docutils literal notranslate"><span class="pre">easy-fs</span></code> 中引入 <code class="docutils literal notranslate"><span class="pre">log</span></code> crate，通过 <code class="docutils literal notranslate"><span class="pre">log::info!/debug!</span></code> 等宏即可进行调试并在内核中看到日志输出。具体来说，在 <code class="docutils literal notranslate"><span class="pre">easy-fs</span></code> 中的修改是：在 <code class="docutils literal notranslate"><span class="pre">easy-fs/Cargo.toml</span></code> 的依赖中加入一行 <code class="docutils literal notranslate"><span class="pre">log</span> <span class="pre">=</span> <span class="pre">"0.4.0"</span></code>，然后在 <code class="docutils literal notranslate"><span class="pre">easy-fs/src/lib.rs</span></code> 中加入一行 <code class="docutils literal notranslate"><span class="pre">extern</span> <span class="pre">crate</span> <span class="pre">log</span></code> 。</p>
<p>你也可以完全在用户态进行调试。仿照 <code class="docutils literal notranslate"><span class="pre">easy-fs-fuse</span></code> 建立一个在当前操作系统中运行的应用程序，将测试逻辑写在 <code class="docutils literal notranslate"><span class="pre">main</span></code> 函数中。这个时候就可以将它引用的 <code class="docutils literal notranslate"><span class="pre">easy-fs</span></code> 的 <code class="docutils literal notranslate"><span class="pre">no_std</span></code> 去掉并使用 <code class="docutils literal notranslate"><span class="pre">println!</span></code> 进行调试。</p>

</ul>
<p>在 <code class="docutils literal notranslate"><span class="pre">YOUR_LAB4_REPO_DIR</span></code> 下进行编码（可学习参考 <code class="docutils literal notranslate"><span class="pre">os6-ref/src</span></code> 目录下的源代码，并在 <code class="docutils literal notranslate"><span class="pre">os6/src</span></code> 中完成编码），并进行编译测试。</p>
<p>注意：本次实验需要扩展文件系统的功能，所以，除了需要修改扩展 <code class="docutils literal notranslate"><span class="pre">os6</span></code> 目录下的代码外，还需要修改扩展 <code class="docutils literal notranslate"><span class="pre">easy-fs</span></code> 和 <code class="docutils literal notranslate"><span class="pre">easy-fs-fuse</span></code> 下面的部分代码。</p>

<p><strong>测试方式</strong></p>
<p>你的实现只需且必须通过测例，建议读者感到困惑时先检查测例</p>
<p>如果实现正确，可在项目仓库的根目录下执行 <code class="docutils literal notranslate"><span class="pre">make</span> <span class="pre">test6</span></code> ，应该看到类似如下的显示输出：</p>
