title: Real name of the "container_of" pattern
body: <p>E.g. in Linux driver development one can find the <a href="http://www.kroah.com/log/linux/container_of.html" rel="nofollow"><code>container_of</code></a> macro. In essence it is the reverse operator to an <code>-&gt;</code>, yielding the pointer to the containing structure if you got a pointer to a member.</p>
  
  <p>Besides from Greg Kroah's blog I found this pattern in the <a href="https://github.com/mehlis/Pintos/blob/621497/src/lib/kernel/list.h" rel="nofollow">list</a> and <a href="https://github.com/mehlis/Pintos/blob/621497/src/lib/kernel/hash.h" rel="nofollow">hash</a> implementation of Pintos.</p>
