Hey Kay,
Your patch that converts the xen-balloon to use the regular device bus driver (070680218379e15c1901f4bf21b98e3cbf12b527) has some not-so-happy consequences.
The toolstack (xen-tools) use:
/sys/devices/system/xen_memory/xen_memory0
But with the change, it is now:
/sys/devices/xen_memory0/target_kb
Which means that the tools can't find it now.
I did not see anything in feature-removal-schedule.txt so I don't know exactly when the full sys_device structure is going away.
Is there any work-arounds that can be inserted in the kernel so that the old directory still exists at least for 3.3 such that there will be enough time for the tool-stack to be updated?
