bugfix for memory controller: add helper function for assigning cgroup to page
This patch adds following functions.
- clear_page_cgroup(page, pc)
- page_cgroup_assign_new_page_group(page, pc)
Mainly for cleanup.
A manner "check page->cgroup again after lock_page_cgroup()" is
implemented in straight way.
A comment in mem_cgroup_uncharge() will be removed by force-empty patch
