Subject: [merged] memcg-rename-high-level-charging-functions.patch removed from -mm tree To: mhocko@xxxxxxx,hannes@xxxxxxxxxxx,mm-commits@xxxxxxxxxxxxxxx From: akpm@xxxxxxxxxxxxxxxxxxxx Date: Tue, 08 Apr 2014 13:54:22 -0700 The patch titled Subject: memcg: rename high level charging functions has been removed from the -mm tree. Its filename was memcg-rename-high-level-charging-functions.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Michal Hocko <mhocko@xxxxxxx> Subject: memcg: rename high level charging functions mem_cgroup_newpage_charge is used only for charging anonymous memory so it is better to rename it to mem_cgroup_charge_anon. mem_cgroup_cache_charge is used for file backed memory so rename it to mem_cgroup_charge_file.
