title: how to build liburing
body: <p>I am build liburing which is a user interface for io_uring features.
  But when I run <code>./configure</code> it throws this error:</p>
  <pre class="lang-sh prettyprint-override"><code>/tmp/fio-conf--21449-.c:2:10: fatal error: linux/time_types.h: No such file or directory
   #include &lt;linux/time_types.h&gt;
            ^~~~~~~~~~~~~~~~~~~~
  compilation terminated.
  
  </code></pre>
  <p>but I found in</p>
  <pre class="lang-sh prettyprint-override"><code>/usr/src/linux-headers-5.3.0-46-generic/include/uapi/linux$ ls time_types.h 
  time_types.h
  </code></pre>
  <p>My kernal version is</p>
  <pre class="lang-sh prettyprint-override"><code>uname -rs
  Linux 5.3.0-46-generic
  
  </code></pre>
  <p>I'm sure that the 5.3 version is supporting io_uring (which has already been supported by 5.1)</p>
  <p>so how to Update kernel/libc headers to support this?</p>
