Hi all, I was going through the slides "Integrating KVM with the linux memory management" on MMU notifiers.
can anyone tell me ... if spte is invisible to linux vm, then why does page->_mapcount increments when a spte mapping is created ? is it done explicitly by the kvm code (if so, why) ? do references to any page from a kernel data-structure (spte in this case) don't involve access though page table entries (hence try_to_unmap() can't unmap those references) ? which makes any page referenced through kernel structures unswappable ? -- Thanks and Regards, Sukanto Ghosh -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
