[Xen-devel] do_mmu_update
Hello friends, Can anyone please tell me what the not_a_pt: label in do_mmu_update used for?
default: not_a_pt: { if ( unlikely(!get_page_type(page, PGT_writable_page)) )
break;
perfc_incr(writable_mmu_updates); okay = paging_write_guest_entry(v, va, req.val, _mfn(mfn)); put_page_type(page);
} break;
Regards, Furquan
