[Xen-devel] Q: XENMEM_maximum_reservation

[Jimi Xenidis <jimix@xxxxxxxxxxxxxx>]

AFAICT, XENMEM_current_reservation and XENMEM_maximum_reservation are  
not used by Linux.
However, if they were do we have to pass the domid_t as a pointer?  
could we not pass it by value?
file: xen/common/memory.c: 369
Rather than
        if ( copy_from_guest(&domid, arg, 1) )

how about:
        domid = (domid_t)arg;

thoughts?
