Hello,

not_a_pt this one will decide that whether before writing to the mmu ,the page type is matching all the conditions or not.

Thanks

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
