Re: [Xen-devel] [RFC][PATCH] Basic support for page offline

Frank, can you please elabrate what's the status mean? What's the usage by Solaris FMA code? Do you mean how the page is used (i.e. information in the page_info->count_info)?
As for the ownership of the page, I'm not sure if we can do that without trying 
online/offline it, since the page may be assigned to another guest after the 
query if it is not marked offline-pending (mark offline pending make sure it 
will not be used anymore if freed).

The usage is pretty simple: there is an interface to:

* retire a page
* unretire a page
* check on the status

The status doesn't have to have much info. The Solaris interface returns one of:

* retired
* not retired
* pending
* invalid page

I understand that the owner may be harder to return, and it isn't really important, so it doesn't matter if that information is not available from the hypercall.
