title: What is alternative of create_proc_entry()
body: <p>As <code>create_proc_entry</code> function is deprecated, what is its replacement?
  I was trying to create a simple proc entry using <code>create_proc_entry</code> but got the this error:</p>
  
  <blockquote>
    <p>error: implicit declaration of function ‘create_proc_entry’</p>
  </blockquote>
  
  <p>I grepped <code>create_proc_entry</code> in proc_fs.h but didn't find it there. Is there something that I'm missing or there's alternative to do this?</p>
