This is v5. Sorry for delaying...but I had time for resetting myself and..several changes are added. I think this version is simpler than v4. Major changes from v4 is a) added kernel/cgroup.c hooks again. (for b) b) make RCU aware. previous version seems dangerous in an extreme case. Then, codes are updated. Most of changes are related to RCU. Patch brief view: 1. add hooks to kernel/cgroup.c for ID management. 2. use ID-array in memcg. 3. record ID to page_cgroup rather than pointer. 4. make update_file_mapped to be RCU aware routine instead of spinlock. 5. make update_file_mapped as general-purpose function.
