From 35b91cb0131f9c63141a887d5dbb7657f01d8808 Mon Sep 17 00:00:00 2001
From: Paolo Valente <paolo.valente@unimore.it>
Date: Tue, 3 Sep 2013 16:50:42 +0200
Subject: [PATCH 1/3] block: cgroups, kconfig, build bits for BFQ-v7r5-3.13
Update Kconfig.iosched and do the related Makefile changes to include
kernel configuration options for BFQ. Also add the bfqio controller
to the cgroups subsystem.
