Subject: [PATCH 7/7] net: change type of virtio_chan->p9_max_pages
Date: Wed, 06 Feb 2013 13:21:56 +0800 [thread overview]
Message-ID: <5111E874.5020703@cn.fujitsu.com> (raw)
In-Reply-To: <5111E612.4010907@cn.fujitsu.com>
This member of struct virtio_chan is calculated from nr_free_buffer_pages
so change its type to unsigned long in case of overflow.
