body: <p>i am using proc_dir_entry in linux 3.13 but i got this error "dereferencing pointer to incomplete type" in this lines of code :</p>
  
  <pre><code>  struct proc_dir_entry *proc = proc_create("hello_proc", 0, NULL, &amp;hello_proc_fops);
      printk(KERN_DEBUG "name : %s\n",proc-&gt;name);
  </code></pre>
