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? -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
