4  * Device for creating grant references (in user-space) that may be shared
20  * Linux userspace programs cannot create grant references.
24  *   Y -> mapping the grant from X
27  *   2. X creates an entry in the grant table that says domid(Y) can access P.
28  *      This is done without a hypercall unless the grant table needs expansion.
29  *   3. X gives the grant reference identifier, GREF, to Y.
39  *   The grant allocation and mmap()ing are, naturally, two separate operations.
43  * WARNING: Since Xen does not allow a guest to forcibly end the use of a grant
44  * reference, this device can be used to consume kernel memory by leaving grant
48  * grant operation.
