Subject: [PATCH 2/13] hrtimer: convert kvm to the new hrtimer apis
Date: Mon, 1 Sep 2008 16:05:48 -0700 [thread overview]
Message-ID: <20080901160548.05986488@infradead.org> (raw)
In-Reply-To: <20080901160343.75a89ec9@infradead.org>
From: Arjan van de Ven <arjan@linux.intel.com>
Subject: [PATCH] hrtimer: convert kvm to the new hrtimer apis
In order to be able to do range hrtimers we need to use accessor functions
to the "expire" member of the hrtimer struct.
This patch converts KVM to these accessors.
