title: verifying where 'kworker/n:n' (in ps -aux) is invoked from
body: <p>In the result of 'ps -aux', I couldn't find how to verify that 'kworker/...' are created from and what module/functions are related to it.</p>
  
  <p>Please let me know how I find out kworkers are from with pid or else.</p>
  
  <p>I've try to check files in /proc, nothing is shown about this.</p>
  
  <pre><code>$ ps -aux | grep kworker
