Re: [Xen-devel] Who uses xc_gnttab_map_grant_refs?

["Derek Murray" <Derek.Murray@xxxxxxxxxxxx>]

Mea culpa for that bit of API. I think this is a case where the
underlying implementation makes it possible, so I decided to make it
available through the user API. No particular reason for it, so I have
no objection to it being simplified (or wrapped by an additional API
function).

Regards,

Derek Murray.
