Subject: [PATCH 0/2] Move kfree_rcu out of rcu code and use kfree_bulk

From: Rao Shoaib <rao.shoaib@...cle.com>

This patch moves kfree_call_rcu() out of rcu related code to
mm/slab_common and updates kfree_rcu() to use new bulk memory free
functions as they are more efficient.

This is a resubmission of the previous patch.

Changes:

1) checkpatch.pl has been fixed, so kfree_rcu macro is much simpler

2) To handle preemption, preempt_enable()/preempt_disable() statements
   have been added to __rcu_bulk_free().


Rao Shoaib (2):
  Move kfree_call_rcu() to slab_common.c
  kfree_rcu() should use kfree_bulk() interface
