title: Insmod string parameter with whitespace
body: <p>hi I learn module these day. Today I write a simple module that would take string parameter when using insmod here is code snippet:</p>
  
  <pre><code>....
  static char *city = "NULL";
  MODULE_PARM(city, charp,0000);
  ....
  </code></pre>
  
  <p>when I type in command line</p>
  
  <pre><code>insmod modulename.ko city="newyork"
  </code></pre>
  
  <p>it's ok</p>
  
  <p>but when I type</p>
  
  <pre><code>insmod modulename.ko city="new york" 
  </code></pre>
  
  <p>there is error</p>
  
  <pre><code>insmod: error inserting 'modulename.ko': -1 Unknown symbol in module
  </code></pre>
  
  <p>do you know why?</p>
