Hi Kirill, I thought we can always get from the page to the VMA. rmap provides this to us via page->mapping and the 'struct address_space' or anon_vma. Do we agree on that? We can also get from the vma to the mm very easily, via vma->vm_mm, right? We can also get from a task to the container quite easily. So, the only question becomes whether there is a 1:1 relationship between mm_structs and containers. Does each mm_struct belong to one and only one container? Basically, can a threaded process have different threads in different containers? It seems that we could bridge the gap pretty easily by either assigning each mm_struct to a container directly, or putting some kind of task-to-mm lookup. Perhaps just a list like mm->tasks_using_this_mm_list.
