Removes the entry <em class="parameter"><code>name</code></em> in the directory
<em class="parameter"><code>parent</code></em> from the procfs. Entries are
removed by their <span class="emphasis"><em>name</em></span>, not by the
<span class="structname">struct proc_dir_entry</span> returned by the
various create functions. Note that this function doesn't
recursively remove entries.
</p><p>
Be sure to free the <em class="structfield"><code>data</code></em> entry from
the <span class="structname">struct proc_dir_entry</span> before
<code class="function">remove_proc_entry</code> is called (that is: if
there was some <em class="structfield"><code>data</code></em> allocated, of
course). See <a class="xref" href="ch03s03.html" title="A single call back for many files">the section called “A single call back for many files”</a> for more information
on using the <em class="structfield"><code>data</code></em> entry.
