title: LCK information on Linux
body: <p>The <code>prstat</code> command in Solaris has the "LCK" field - essentially the time that a process or thread waited for a user-level lock. What can I use in Linux to get the same information? I looked at <code>top</code>, <code>htop</code> and <code>pstree</code> but none output something like the LCK.</p>
  
  <p>The bottomline is that I would like to replicate this profiling method: <a href="http://www.oracle.com/technetwork/articles/servers-storage-dev/mem-alloc-1557798.html" rel="nofollow">http://www.oracle.com/technetwork/articles/servers-storage-dev/mem-alloc-1557798.html</a>, but this time on Linux.</p>
