Subject: [PATCH 17/25] io-controller: deadline changes for hierarchical fair queuing
Date: Thu, 2 Jul 2009 16:01:49 -0400 [thread overview]
Message-ID: <1246564917-19603-18-git-send-email-vgoyal@redhat.com> (raw)
In-Reply-To: <1246564917-19603-1-git-send-email-vgoyal@redhat.com>
This patch changes deadline to use queue scheduling code from elevator layer.
One can go back to old deadline by selecting CONFIG_IOSCHED_DEADLINE_HIER.
