Subject: [PATCH 0/2] modify the order of resetting/deassigning device.
Date: Fri, 24 Apr 2009 17:40:29 +0900	[thread overview]
Message-ID: <20090424173938.B651.27C06F64@necst.nec.co.jp> (raw)
In-Reply-To: <C615ECDE.9492%keir.fraser@eu.citrix.com>

This series of patches modify the order of resetting/deassigning
device.

I modify the order of resetting/deassigning device like below.

  When guest OS shutdowns or a device is hotremoved.
   1. Xend resets devices.
   2. Xend deassigns devices.

Because if devices are deassigned before the reset, dom0 memory may be
broken by DMA

Thanks,
