Thanks for your suggestion, i will pay more attention on it in the further.
For this patch, what did you mean of "those"? You mean the whole rmap.PTE_LIST_WP_BIT (fast check for shadow page table write protection and host write protection) or just about host_page_write_protect (for KSM only)?
If we do not have rmap.PTE_LIST_WP_BIT, there may have regression on shadow mmu.
Hmm, do i need implement rmap.PTE_LIST_WP_BIT, then fast page fault?
