Hi. > At first look, remembering mm struct is not very good. > Remembering swap controller itself is better. The swap_cgroup when the page(and page_cgroup) is allocated and the swap_cgroup when the page is going to be swapped out may be different by swap_cgroup_move_task(), so I think swap_cgroup to be charged should be determined at the point of swapout. Instead of pointing mm_struct from page_cgroup, it would be better to determine the mm_struct which the page to be swapped out is belongs to by rmap, and charge swap_cgroup of the mm_struct. In this implementation, I don't need to add new member to page_cgroup. What do you think ?
