invalidate_range_begin/end. Then we can return to an older approach of doing only invalidate_page and serializing it with the PT lock against get_user_pages. That works fine for KVM but GRU will have to flush the tlb once every time we drop the PT lock, that means once per each 512 ptes on x86-64 etc... instead of a single time for the whole range regardless how large the range is. | ||||||||||
