From bd845e38c7a7251a95a8f2c38aa7fb87140b771d Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Tue, 4 Mar 2008 14:29:01 -0800 Subject: [PATCH] memcg: mm_match_cgroup not vm_match_cgroup vm_match_cgroup is a perverse name for a macro to match mm with cgroup: rename it mm_match_cgroup, matching mm_init_cgroup and mm_free_cgroup.
