confused about the balloon code
hi
I try to understand the code of balloon ,and got confused about the
following parts of code:
static int decrease_reservation(unsigned long nr_pages)
{

if (!PageHighMem(page)) {
v = phys_to_virt(pfn << PAGE_SHIFT);
scrub_pages(v, 1);
ret = HYPERVISOR_update_va_mapping(
(unsigned long)v, __pte_ma(0), 0);
