[Xen-devel] new gnttab_end_foreign_access?

[NAHieu <nahieu@xxxxxxxxx>]

Hi,

In grant-table API, gnttab_end_foreign_access() is used to end the
access to grant reference got from  gnttab_grant_foreign_access(domid,
mfn, readonly)

But the new gnttab_end_foreign_access(ref, page, readonly) (checked in
few days ago) required the new "page" arg. I understand that this"page
" is actually the arg "mfn" from the above gnttab_grant_foreign_access
function(), right?

If that is the case, there is only one ref corresponding to a page,
why we need this new arg?

Many thanks.
Hieu
