[akpm at linux-foundation.org]

The patch titled
     Use task_pgrp() task_session() in copy_process()
has been removed from the -mm tree.  Its filename was
     use-task_pgrp-task_session-in-copy_process.patch

------------------------------------------------------
Subject: Use task_pgrp() task_session() in copy_process()
From: Sukadev Bhattiprolu <sukadev at us.ibm.com>

Use task_pgrp() and task_session() in copy_process(), and avoid find_pid()
call when attaching the task to its process group and session.
