Dlocking.rst58 What we use to avoid all the race is the Host-writable bit and MMU-writable bit
61 - Host-writable means the gfn is writable in the host kernel page tables and in
63 - MMU-writable means the gfn is writable in the guest's mmu and it is not
123 - The pfn is writable and therefore it cannot be shared between different gfns
135 writable between reading spte and updating spte. Like below case:
182 If the spte is updated from writable to readonly, we should flush all TLBs,
184 writable spte might be cached on a CPU's TLB.
186 As mentioned before, the spte can be updated to writable out of mmu-lock on
