tt->mm_struct is filled in task_mm(), I think we can use this:<br>
<br>
   mm_count = INT(tt->mm_struct + OFFSET(mm_struct_mm_count));<br>
<br>
The following code in get_task_mem_usage() also use this.<br></blockquote><div><br></div><div>Good idea. I will post v2 with this change later.</div><div><br></div><div>Thanks.</div><div>Lianbo</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
