Hi, Keir,
The following patch is from Ian Campbell, sent at Fri 5/8/2009 5:03 PM.
This path doesn't exist in the pvops kernel. Looks
like /sys/bus/xen-backend/devices is just as good and exists in both
pvops and 2.6.18 kernels.
Subject: xenstat: Use backend path which is compatible with pvops and
2.6.18-xen kernels.
