Subject: [Qemu-devel] [PATCH 1/2] [virtio-9p] Cleanup legacy 'dotu' variable.
Date: Tue, 13 Jul 2010 16:24:41 +0530 [thread overview]
Message-ID: <20100713105441.GA11854@linux.vnet.ibm.com> (raw)
Hi,
This patch cleans up the legacy 'dotu' variable which is always set to
1 by default, since qemu doesnt support legacy 9p clients.
