Should we move all of our proc entries from /proc/xen to /proc/sys/xen ?
It's argable this this would be more consistent.

If it should mostly be sysfs'ified anyway, let's wait for xenbus and do 
it properly then.

I'm not sure doing ioctls on empty files in /proc is ever going to be 
particularly consistent :-(  I'd argue things like privcmd really ought to be 
a device.

I suspect the balloon driver file could usefully live with the VM settings - 
as Rik said, such a device could be useful for other VMMs.

Yup.

While we're on the subject, what's everyone's thoughts on exporting 
domain information within sysfs in a /proc/<pid> style (perhaps 
/sys/xen/<domid>) instead of exposing the getdomaininfo hypercall to 
userspace?  While Linux-centric, it provides a pretty clean way to make 
sure that we can always query settable information.

I had put this on my todo list.  I think it should be in sysfs.
