[Xen-devel] Grant table version

[Vladimir 'Ï-coder/phcoder' Serbinenko <phcoder@xxxxxxxxx>]

Hello, all. I'm working on pvgrub2 and my problem is following:
When you first use grant tables you commit yourself to a particular
grant table version. GRUB has to read from disk and hence use grant
tables. By doing so it commits anything that it loads to the same version.
Would it be possible to have a hypercall to reset grant table version?
Of course, before doing such a call one would need to revoke all grants
or this call would discard all current grants.
