title: Linux Kernel Programming Book for 3.x versions
body: <p>I'm Trying to develop linux kernel module for my own server.
  I have a Ubuntu with linux kernel 3.4, but I can't find any books or tutorials for developing modules on 3.x versions, all tutorials and books are for 2.x versions.
  <br/>
  And the most part of code not compiling on 3.4 version, specially kernel threads parts.
  <br/><br/>
  Do you know anything that would be useful to understand 3.x module development ?
  <br/><br/>
  Thanks.</p>
