title: sysinfo struct in linux/kernel.h
body: <p>I was snooping around looking at various kernel header files and stumbled across <code>&lt;linux/kernel.h&gt;</code>. Inside it is a structure called <code>sysinfo</code>. </p>
  
  <p>I've tried using it out of the box so to speak and all the values in the structure returned 0. Im guessing I need to use the poplating function above called <code>do_sysinfo(struct sysinfo *info)</code>. </p>
  
  <p>The thing is I can't find any info which references how to use it. I tried the function out of the box and it failed because it couldn't be linked. Anyone have any information about how to use this or why it's failing? I am a newbie in this area. Would like any links to good guides/info if you have them, that would be great.</p>
