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);
