Randy,

For a case where two or more domains are sharing common resource (i.e shared pages) across domains and needs some kind of locking. This is not using grant ref mechanism but some kind of common shared memory (xenFS). It may require locking if two or more domains use same common machine pages and needs locking.

Thanks
Siva
